Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574624, here are decompositions:

61 + 31574563 = 31574624
127 + 31574497 = 31574624
157 + 31574467 = 31574624
181 + 31574443 = 31574624
421 + 31574203 = 31574624
577 + 31574047 = 31574624
877 + 31573747 = 31574624
997 + 31573627 = 31574624

Showing the first eight; more decompositions exist.
