Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608370, here are decompositions:

29 + 31608341 = 31608370
107 + 31608263 = 31608370
239 + 31608131 = 31608370
263 + 31608107 = 31608370
401 + 31607969 = 31608370
449 + 31607921 = 31608370
461 + 31607909 = 31608370
467 + 31607903 = 31608370

Showing the first eight; more decompositions exist.
