Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546184, here are decompositions:

  • 3 + 31546181 = 31546184
  • 31 + 31546153 = 31546184
  • 73 + 31546111 = 31546184
  • 193 + 31545991 = 31546184
  • 283 + 31545901 = 31546184
  • 421 + 31545763 = 31546184
  • 577 + 31545607 = 31546184
  • 811 + 31545373 = 31546184

Showing the first eight; more decompositions exist.
