Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608698, here are decompositions:

31 + 31608667 = 31608698
109 + 31608589 = 31608698
271 + 31608427 = 31608698
349 + 31608349 = 31608698
379 + 31608319 = 31608698
397 + 31608301 = 31608698
607 + 31608091 = 31608698
631 + 31608067 = 31608698

Showing the first eight; more decompositions exist.
