Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561698, here are decompositions:

31 + 561667 = 561698
139 + 561559 = 561698
331 + 561367 = 561698
421 + 561277 = 561698
499 + 561199 = 561698
601 + 561097 = 561698
607 + 561091 = 561698
619 + 561079 = 561698

Showing the first eight; more decompositions exist.
