Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476574, here are decompositions:

23 + 31476551 = 31476574
113 + 31476461 = 31476574
137 + 31476437 = 31476574
191 + 31476383 = 31476574
257 + 31476317 = 31476574
431 + 31476143 = 31476574
461 + 31476113 = 31476574
557 + 31476017 = 31476574

Showing the first eight; more decompositions exist.
