Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615598, here are decompositions:

109 + 31615489 = 31615598
127 + 31615471 = 31615598
181 + 31615417 = 31615598
199 + 31615399 = 31615598
277 + 31615321 = 31615598
709 + 31614889 = 31615598
739 + 31614859 = 31615598
769 + 31614829 = 31615598

Showing the first eight; more decompositions exist.
