Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514598, here are decompositions:

19 + 31514579 = 31514598
47 + 31514551 = 31514598
61 + 31514537 = 31514598
149 + 31514449 = 31514598
179 + 31514419 = 31514598
197 + 31514401 = 31514598
307 + 31514291 = 31514598
331 + 31514267 = 31514598

Showing the first eight; more decompositions exist.
