Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574126, here are decompositions:

19 + 31574107 = 31574126
79 + 31574047 = 31574126
127 + 31573999 = 31574126
307 + 31573819 = 31574126
373 + 31573753 = 31574126
379 + 31573747 = 31574126
487 + 31573639 = 31574126
499 + 31573627 = 31574126

Showing the first eight; more decompositions exist.
