Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609652, here are decompositions:

43 + 31609609 = 31609652
103 + 31609549 = 31609652
199 + 31609453 = 31609652
271 + 31609381 = 31609652
313 + 31609339 = 31609652
421 + 31609231 = 31609652
439 + 31609213 = 31609652
463 + 31609189 = 31609652

Showing the first eight; more decompositions exist.
