Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609598, here are decompositions:

37 + 31609561 = 31609598
67 + 31609531 = 31609598
79 + 31609519 = 31609598
331 + 31609267 = 31609598
367 + 31609231 = 31609598
409 + 31609189 = 31609598
487 + 31609111 = 31609598
661 + 31608937 = 31609598

Showing the first eight; more decompositions exist.
