Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556026, here are decompositions:

59 + 31555967 = 31556026
149 + 31555877 = 31556026
263 + 31555763 = 31556026
419 + 31555607 = 31556026
587 + 31555439 = 31556026
773 + 31555253 = 31556026
797 + 31555229 = 31556026
839 + 31555187 = 31556026

Showing the first eight; more decompositions exist.
