Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617044, here are decompositions:

31 + 31617013 = 31617044
127 + 31616917 = 31617044
157 + 31616887 = 31617044
271 + 31616773 = 31617044
337 + 31616707 = 31617044
367 + 31616677 = 31617044
373 + 31616671 = 31617044
397 + 31616647 = 31617044

Showing the first eight; more decompositions exist.
