Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147566980, here are decompositions:

  • 11 + 2147566969 = 2147566980
  • 19 + 2147566961 = 2147566980
  • 43 + 2147566937 = 2147566980
  • 127 + 2147566853 = 2147566980
  • 137 + 2147566843 = 2147566980
  • 149 + 2147566831 = 2147566980
  • 151 + 2147566829 = 2147566980
  • 199 + 2147566781 = 2147566980

Showing the first eight; more decompositions exist.
