Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556302, here are decompositions:

23 + 31556279 = 31556302
53 + 31556249 = 31556302
59 + 31556243 = 31556302
101 + 31556201 = 31556302
269 + 31556033 = 31556302
311 + 31555991 = 31556302
353 + 31555949 = 31556302
431 + 31555871 = 31556302

Showing the first eight; more decompositions exist.
