Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582088, here are decompositions:

61 + 31582027 = 31582088
67 + 31582021 = 31582088
127 + 31581961 = 31582088
199 + 31581889 = 31582088
211 + 31581877 = 31582088
229 + 31581859 = 31582088
271 + 31581817 = 31582088
379 + 31581709 = 31582088

Showing the first eight; more decompositions exist.
