Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731122, here are decompositions:

  • 11 + 8731111 = 8731122
  • 13 + 8731109 = 8731122
  • 19 + 8731103 = 8731122
  • 53 + 8731069 = 8731122
  • 83 + 8731039 = 8731122
  • 139 + 8730983 = 8731122
  • 173 + 8730949 = 8731122
  • 193 + 8730929 = 8731122

Showing the first eight; more decompositions exist.
