Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588698, here are decompositions:

5 + 31588693 = 31588698
19 + 31588679 = 31588698
41 + 31588657 = 31588698
67 + 31588631 = 31588698
137 + 31588561 = 31588698
227 + 31588471 = 31588698
257 + 31588441 = 31588698
331 + 31588367 = 31588698

Showing the first eight; more decompositions exist.
