Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575034, here are decompositions:

53 + 31574981 = 31575034
107 + 31574927 = 31575034
173 + 31574861 = 31575034
311 + 31574723 = 31575034
347 + 31574687 = 31575034
353 + 31574681 = 31575034
503 + 31574531 = 31575034
773 + 31574261 = 31575034

Showing the first eight; more decompositions exist.
