Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617248, here are decompositions:

67 + 31617181 = 31617248
199 + 31617049 = 31617248
331 + 31616917 = 31617248
409 + 31616839 = 31617248
499 + 31616749 = 31617248
541 + 31616707 = 31617248
571 + 31616677 = 31617248
577 + 31616671 = 31617248

Showing the first eight; more decompositions exist.
