Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574506, here are decompositions:

17 + 31574489 = 31574506
53 + 31574453 = 31574506
137 + 31574369 = 31574506
179 + 31574327 = 31574506
647 + 31573859 = 31574506
653 + 31573853 = 31574506
659 + 31573847 = 31574506
683 + 31573823 = 31574506

Showing the first eight; more decompositions exist.
