Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616854, here are decompositions:

107 + 31616747 = 31616854
167 + 31616687 = 31616854
251 + 31616603 = 31616854
293 + 31616561 = 31616854
431 + 31616423 = 31616854
443 + 31616411 = 31616854
461 + 31616393 = 31616854
491 + 31616363 = 31616854

Showing the first eight; more decompositions exist.
