Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619278, here are decompositions:

  • 37 + 8619241 = 8619278
  • 67 + 8619211 = 8619278
  • 79 + 8619199 = 8619278
  • 127 + 8619151 = 8619278
  • 181 + 8619097 = 8619278
  • 211 + 8619067 = 8619278
  • 541 + 8618737 = 8619278
  • 991 + 8618287 = 8619278

Showing the first eight; more decompositions exist.
