Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574460, here are decompositions:

7 + 31574453 = 31574460
11 + 31574449 = 31574460
17 + 31574443 = 31574460
23 + 31574437 = 31574460
31 + 31574429 = 31574460
41 + 31574419 = 31574460
97 + 31574363 = 31574460
131 + 31574329 = 31574460

Showing the first eight; more decompositions exist.
