Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617260, here are decompositions:

7 + 31617253 = 31617260
61 + 31617199 = 31617260
79 + 31617181 = 31617260
127 + 31617133 = 31617260
211 + 31617049 = 31617260
331 + 31616929 = 31617260
373 + 31616887 = 31617260
421 + 31616839 = 31617260

Showing the first eight; more decompositions exist.
