Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588292, here are decompositions:

163 + 31588129 = 31588292
313 + 31587979 = 31588292
331 + 31587961 = 31588292
349 + 31587943 = 31588292
433 + 31587859 = 31588292
499 + 31587793 = 31588292
859 + 31587433 = 31588292
1021 + 31587271 = 31588292

Showing the first eight; more decompositions exist.
