Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609670, here are decompositions:

61 + 31609609 = 31609670
109 + 31609561 = 31609670
139 + 31609531 = 31609670
151 + 31609519 = 31609670
277 + 31609393 = 31609670
331 + 31609339 = 31609670
439 + 31609231 = 31609670
457 + 31609213 = 31609670

Showing the first eight; more decompositions exist.
