Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556462, here are decompositions:

73 + 31556389 = 31556462
109 + 31556353 = 31556462
139 + 31556323 = 31556462
313 + 31556149 = 31556462
349 + 31556113 = 31556462
463 + 31555999 = 31556462
523 + 31555939 = 31556462
541 + 31555921 = 31556462

Showing the first eight; more decompositions exist.
