Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614390, here are decompositions:

13 + 31614377 = 31614390
19 + 31614371 = 31614390
37 + 31614353 = 31614390
47 + 31614343 = 31614390
107 + 31614283 = 31614390
113 + 31614277 = 31614390
163 + 31614227 = 31614390
173 + 31614217 = 31614390

Showing the first eight; more decompositions exist.
