Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609384, here are decompositions:

3 + 31609381 = 31609384
293 + 31609091 = 31609384
353 + 31609031 = 31609384
431 + 31608953 = 31609384
467 + 31608917 = 31609384
491 + 31608893 = 31609384
563 + 31608821 = 31609384
647 + 31608737 = 31609384

Showing the first eight; more decompositions exist.
