Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612988, here are decompositions:

  • 5 + 8612983 = 8612988
  • 19 + 8612969 = 8612988
  • 29 + 8612959 = 8612988
  • 31 + 8612957 = 8612988
  • 47 + 8612941 = 8612988
  • 61 + 8612927 = 8612988
  • 127 + 8612861 = 8612988
  • 149 + 8612839 = 8612988

Showing the first eight; more decompositions exist.
