Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535588, here are decompositions:

37 + 31535551 = 31535588
211 + 31535377 = 31535588
277 + 31535311 = 31535588
457 + 31535131 = 31535588
577 + 31535011 = 31535588
607 + 31534981 = 31535588
709 + 31534879 = 31535588
757 + 31534831 = 31535588

Showing the first eight; more decompositions exist.
