Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574562, here are decompositions:

31 + 31574531 = 31574562
73 + 31574489 = 31574562
83 + 31574479 = 31574562
109 + 31574453 = 31574562
113 + 31574449 = 31574562
193 + 31574369 = 31574562
199 + 31574363 = 31574562
233 + 31574329 = 31574562

Showing the first eight; more decompositions exist.
