Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617074, here are decompositions:

61 + 31617013 = 31617074
157 + 31616917 = 31617074
367 + 31616707 = 31617074
397 + 31616677 = 31617074
673 + 31616401 = 31617074
787 + 31616287 = 31617074
823 + 31616251 = 31617074
1033 + 31616041 = 31617074

Showing the first eight; more decompositions exist.
