Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618088, here are decompositions:

31 + 31618057 = 31618088
127 + 31617961 = 31618088
199 + 31617889 = 31618088
211 + 31617877 = 31618088
277 + 31617811 = 31618088
331 + 31617757 = 31618088
409 + 31617679 = 31618088
421 + 31617667 = 31618088

Showing the first eight; more decompositions exist.
