Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574302, here are decompositions:

5 + 31574297 = 31574302
41 + 31574261 = 31574302
101 + 31574201 = 31574302
281 + 31574021 = 31574302
443 + 31573859 = 31574302
449 + 31573853 = 31574302
479 + 31573823 = 31574302
509 + 31573793 = 31574302

Showing the first eight; more decompositions exist.
