Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556062, here are decompositions:

29 + 31556033 = 31556062
71 + 31555991 = 31556062
113 + 31555949 = 31556062
191 + 31555871 = 31556062
281 + 31555781 = 31556062
401 + 31555661 = 31556062
431 + 31555631 = 31556062
491 + 31555571 = 31556062

Showing the first eight; more decompositions exist.
