Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588302, here are decompositions:

101 + 31588201 = 31588302
103 + 31588199 = 31588302
131 + 31588171 = 31588302
173 + 31588129 = 31588302
199 + 31588103 = 31588302
241 + 31588061 = 31588302
283 + 31588019 = 31588302
353 + 31587949 = 31588302

Showing the first eight; more decompositions exist.
