Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556608, here are decompositions:

71 + 31556537 = 31556608
107 + 31556501 = 31556608
131 + 31556477 = 31556608
191 + 31556417 = 31556608
227 + 31556381 = 31556608
359 + 31556249 = 31556608
467 + 31556141 = 31556608
509 + 31556099 = 31556608

Showing the first eight; more decompositions exist.
