Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574502, here are decompositions:

5 + 31574497 = 31574502
13 + 31574489 = 31574502
23 + 31574479 = 31574502
53 + 31574449 = 31574502
59 + 31574443 = 31574502
73 + 31574429 = 31574502
83 + 31574419 = 31574502
139 + 31574363 = 31574502

Showing the first eight; more decompositions exist.
