Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638254, here are decompositions:

  • 7 + 8638247 = 8638254
  • 13 + 8638241 = 8638254
  • 17 + 8638237 = 8638254
  • 41 + 8638213 = 8638254
  • 47 + 8638207 = 8638254
  • 67 + 8638187 = 8638254
  • 71 + 8638183 = 8638254
  • 103 + 8638151 = 8638254

Showing the first eight; more decompositions exist.
