Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609546, here are decompositions:

5 + 31609541 = 31609546
47 + 31609499 = 31609546
53 + 31609493 = 31609546
83 + 31609463 = 31609546
257 + 31609289 = 31609546
317 + 31609229 = 31609546
467 + 31609079 = 31609546
587 + 31608959 = 31609546

Showing the first eight; more decompositions exist.
