Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541292, here are decompositions:

  • 11 + 31541281 = 31541292
  • 23 + 31541269 = 31541292
  • 59 + 31541233 = 31541292
  • 113 + 31541179 = 31541292
  • 131 + 31541161 = 31541292
  • 151 + 31541141 = 31541292
  • 163 + 31541129 = 31541292
  • 179 + 31541113 = 31541292

Showing the first eight; more decompositions exist.
