Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638548, here are decompositions:

  • 5 + 8638543 = 8638548
  • 31 + 8638517 = 8638548
  • 67 + 8638481 = 8638548
  • 71 + 8638477 = 8638548
  • 97 + 8638451 = 8638548
  • 101 + 8638447 = 8638548
  • 137 + 8638411 = 8638548
  • 167 + 8638381 = 8638548

Showing the first eight; more decompositions exist.
