Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617194, here are decompositions:

13 + 31617181 = 31617194
61 + 31617133 = 31617194
181 + 31617013 = 31617194
277 + 31616917 = 31617194
307 + 31616887 = 31617194
337 + 31616857 = 31617194
421 + 31616773 = 31617194
487 + 31616707 = 31617194

Showing the first eight; more decompositions exist.
