Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556632, here are decompositions:

131 + 31556501 = 31556632
251 + 31556381 = 31556632
353 + 31556279 = 31556632
383 + 31556249 = 31556632
389 + 31556243 = 31556632
431 + 31556201 = 31556632
491 + 31556141 = 31556632
599 + 31556033 = 31556632

Showing the first eight; more decompositions exist.
