Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486598, here are decompositions:

61 + 31486537 = 31486598
181 + 31486417 = 31486598
211 + 31486387 = 31486598
271 + 31486327 = 31486598
331 + 31486267 = 31486598
397 + 31486201 = 31486598
709 + 31485889 = 31486598
727 + 31485871 = 31486598

Showing the first eight; more decompositions exist.
