Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620254, here are decompositions:

  • 31 + 31620223 = 31620254
  • 103 + 31620151 = 31620254
  • 241 + 31620013 = 31620254
  • 433 + 31619821 = 31620254
  • 541 + 31619713 = 31620254
  • 571 + 31619683 = 31620254
  • 607 + 31619647 = 31620254
  • 643 + 31619611 = 31620254

Showing the first eight; more decompositions exist.
