Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608654, here are decompositions:

67 + 31608587 = 31608654
127 + 31608527 = 31608654
157 + 31608497 = 31608654
173 + 31608481 = 31608654
227 + 31608427 = 31608654
313 + 31608341 = 31608654
317 + 31608337 = 31608654
353 + 31608301 = 31608654

Showing the first eight; more decompositions exist.
