Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147392634, here are decompositions:

  • 43 + 2147392591 = 2147392634
  • 73 + 2147392561 = 2147392634
  • 103 + 2147392531 = 2147392634
  • 433 + 2147392201 = 2147392634
  • 487 + 2147392147 = 2147392634
  • 613 + 2147392021 = 2147392634
  • 643 + 2147391991 = 2147392634
  • 661 + 2147391973 = 2147392634

Showing the first eight; more decompositions exist.
