Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609846, here are decompositions:

53 + 31609793 = 31609846
167 + 31609679 = 31609846
263 + 31609583 = 31609846
269 + 31609577 = 31609846
347 + 31609499 = 31609846
353 + 31609493 = 31609846
383 + 31609463 = 31609846
557 + 31609289 = 31609846

Showing the first eight; more decompositions exist.
