Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475032, here are decompositions:

3 + 31475029 = 31475032
23 + 31475009 = 31475032
101 + 31474931 = 31475032
269 + 31474763 = 31475032
311 + 31474721 = 31475032
359 + 31474673 = 31475032
431 + 31474601 = 31475032
461 + 31474571 = 31475032

Showing the first eight; more decompositions exist.
