Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608674, here are decompositions:

7 + 31608667 = 31608674
193 + 31608481 = 31608674
337 + 31608337 = 31608674
373 + 31608301 = 31608674
457 + 31608217 = 31608674
541 + 31608133 = 31608674
607 + 31608067 = 31608674
613 + 31608061 = 31608674

Showing the first eight; more decompositions exist.
