Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588598, here are decompositions:

37 + 31588561 = 31588598
127 + 31588471 = 31588598
157 + 31588441 = 31588598
199 + 31588399 = 31588598
229 + 31588369 = 31588598
241 + 31588357 = 31588598
277 + 31588321 = 31588598
331 + 31588267 = 31588598

Showing the first eight; more decompositions exist.
