Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727240, here are decompositions:

  • 29 + 8727211 = 8727240
  • 43 + 8727197 = 8727240
  • 61 + 8727179 = 8727240
  • 79 + 8727161 = 8727240
  • 83 + 8727157 = 8727240
  • 127 + 8727113 = 8727240
  • 131 + 8727109 = 8727240
  • 149 + 8727091 = 8727240

Showing the first eight; more decompositions exist.
