Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588334, here are decompositions:

3 + 31588331 = 31588334
13 + 31588321 = 31588334
31 + 31588303 = 31588334
67 + 31588267 = 31588334
163 + 31588171 = 31588334
331 + 31588003 = 31588334
373 + 31587961 = 31588334
457 + 31587877 = 31588334

Showing the first eight; more decompositions exist.
