Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609462, here are decompositions:

11 + 31609451 = 31609462
173 + 31609289 = 31609462
233 + 31609229 = 31609462
239 + 31609223 = 31609462
383 + 31609079 = 31609462
431 + 31609031 = 31609462
491 + 31608971 = 31609462
503 + 31608959 = 31609462

Showing the first eight; more decompositions exist.
