Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608464, here are decompositions:

37 + 31608427 = 31608464
127 + 31608337 = 31608464
163 + 31608301 = 31608464
193 + 31608271 = 31608464
331 + 31608133 = 31608464
373 + 31608091 = 31608464
397 + 31608067 = 31608464
607 + 31607857 = 31608464

Showing the first eight; more decompositions exist.
