Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514718, here are decompositions:

29 + 31514689 = 31514718
31 + 31514687 = 31514718
47 + 31514671 = 31514718
89 + 31514629 = 31514718
139 + 31514579 = 31514718
167 + 31514551 = 31514718
181 + 31514537 = 31514718
239 + 31514479 = 31514718

Showing the first eight; more decompositions exist.
