Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609432, here are decompositions:

353 + 31609079 = 31609432
383 + 31609049 = 31609432
401 + 31609031 = 31609432
461 + 31608971 = 31609432
479 + 31608953 = 31609432
521 + 31608911 = 31609432
653 + 31608779 = 31609432
683 + 31608749 = 31609432

Showing the first eight; more decompositions exist.
