Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617092, here are decompositions:

19 + 31617073 = 31617092
43 + 31617049 = 31617092
79 + 31617013 = 31617092
163 + 31616929 = 31617092
421 + 31616671 = 31617092
523 + 31616569 = 31617092
571 + 31616521 = 31617092
613 + 31616479 = 31617092

Showing the first eight; more decompositions exist.
