Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609348, here are decompositions:

59 + 31609289 = 31609348
257 + 31609091 = 31609348
269 + 31609079 = 31609348
317 + 31609031 = 31609348
389 + 31608959 = 31609348
431 + 31608917 = 31609348
461 + 31608887 = 31609348
569 + 31608779 = 31609348

Showing the first eight; more decompositions exist.
