Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588202, here are decompositions:

3 + 31588199 = 31588202
31 + 31588171 = 31588202
73 + 31588129 = 31588202
199 + 31588003 = 31588202
223 + 31587979 = 31588202
241 + 31587961 = 31588202
409 + 31587793 = 31588202
421 + 31587781 = 31588202

Showing the first eight; more decompositions exist.
