Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540952, here are decompositions:

13 + 31540939 = 31540952
31 + 31540921 = 31540952
139 + 31540813 = 31540952
229 + 31540723 = 31540952
283 + 31540669 = 31540952
379 + 31540573 = 31540952
463 + 31540489 = 31540952
613 + 31540339 = 31540952

Showing the first eight; more decompositions exist.
