Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588088, here are decompositions:

109 + 31587979 = 31588088
127 + 31587961 = 31588088
139 + 31587949 = 31588088
211 + 31587877 = 31588088
229 + 31587859 = 31588088
271 + 31587817 = 31588088
307 + 31587781 = 31588088
661 + 31587427 = 31588088

Showing the first eight; more decompositions exist.
