Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608684, here are decompositions:

17 + 31608667 = 31608684
97 + 31608587 = 31608684
157 + 31608527 = 31608684
257 + 31608427 = 31608684
347 + 31608337 = 31608684
383 + 31608301 = 31608684
421 + 31608263 = 31608684
467 + 31608217 = 31608684

Showing the first eight; more decompositions exist.
