Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489598, here are decompositions:

79 + 31489519 = 31489598
109 + 31489489 = 31489598
181 + 31489417 = 31489598
199 + 31489399 = 31489598
421 + 31489177 = 31489598
571 + 31489027 = 31489598
607 + 31488991 = 31489598
619 + 31488979 = 31489598

Showing the first eight; more decompositions exist.
