Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536604, here are decompositions:

53 + 31536551 = 31536604
83 + 31536521 = 31536604
251 + 31536353 = 31536604
257 + 31536347 = 31536604
311 + 31536293 = 31536604
317 + 31536287 = 31536604
401 + 31536203 = 31536604
443 + 31536161 = 31536604

Showing the first eight; more decompositions exist.
