Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540532, here are decompositions:

3 + 31540529 = 31540532
31 + 31540501 = 31540532
43 + 31540489 = 31540532
61 + 31540471 = 31540532
193 + 31540339 = 31540532
223 + 31540309 = 31540532
271 + 31540261 = 31540532
409 + 31540123 = 31540532

Showing the first eight; more decompositions exist.
