Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541864, here are decompositions:

7 + 31541857 = 31541864
37 + 31541827 = 31541864
103 + 31541761 = 31541864
127 + 31541737 = 31541864
157 + 31541707 = 31541864
283 + 31541581 = 31541864
307 + 31541557 = 31541864
337 + 31541527 = 31541864

Showing the first eight; more decompositions exist.
