Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588082, here are decompositions:

79 + 31588003 = 31588082
103 + 31587979 = 31588082
139 + 31587943 = 31588082
223 + 31587859 = 31588082
283 + 31587799 = 31588082
661 + 31587421 = 31588082
811 + 31587271 = 31588082
859 + 31587223 = 31588082

Showing the first eight; more decompositions exist.
