Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588846, here are decompositions:

137 + 31588709 = 31588846
167 + 31588679 = 31588846
173 + 31588673 = 31588846
239 + 31588607 = 31588846
353 + 31588493 = 31588846
383 + 31588463 = 31588846
479 + 31588367 = 31588846
593 + 31588253 = 31588846

Showing the first eight; more decompositions exist.
