Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537060, here are decompositions:

11 + 31537049 = 31537060
17 + 31537043 = 31537060
59 + 31537001 = 31537060
101 + 31536959 = 31537060
197 + 31536863 = 31537060
239 + 31536821 = 31537060
353 + 31536707 = 31537060
431 + 31536629 = 31537060

Showing the first eight; more decompositions exist.
