Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587926, here are decompositions:

3 + 31587923 = 31587926
67 + 31587859 = 31587926
109 + 31587817 = 31587926
127 + 31587799 = 31587926
229 + 31587697 = 31587926
499 + 31587427 = 31587926
907 + 31587019 = 31587926
1087 + 31586839 = 31587926

Showing the first eight; more decompositions exist.
