Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608702, here are decompositions:

5 + 31608697 = 31608702
113 + 31608589 = 31608702
173 + 31608529 = 31608702
353 + 31608349 = 31608702
383 + 31608319 = 31608702
401 + 31608301 = 31608702
431 + 31608271 = 31608702
439 + 31608263 = 31608702

Showing the first eight; more decompositions exist.
