Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617206, here are decompositions:

7 + 31617199 = 31617206
73 + 31617133 = 31617206
157 + 31617049 = 31617206
193 + 31617013 = 31617206
277 + 31616929 = 31617206
349 + 31616857 = 31617206
367 + 31616839 = 31617206
433 + 31616773 = 31617206

Showing the first eight; more decompositions exist.
