Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608842, here are decompositions:

19 + 31608823 = 31608842
313 + 31608529 = 31608842
523 + 31608319 = 31608842
541 + 31608301 = 31608842
571 + 31608271 = 31608842
673 + 31608169 = 31608842
709 + 31608133 = 31608842
751 + 31608091 = 31608842

Showing the first eight; more decompositions exist.
