Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609718, here are decompositions:

109 + 31609609 = 31609718
157 + 31609561 = 31609718
199 + 31609519 = 31609718
337 + 31609381 = 31609718
379 + 31609339 = 31609718
487 + 31609231 = 31609718
601 + 31609117 = 31609718
607 + 31609111 = 31609718

Showing the first eight; more decompositions exist.
