Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550454, here are decompositions:

7 + 31550447 = 31550454
17 + 31550437 = 31550454
53 + 31550401 = 31550454
83 + 31550371 = 31550454
97 + 31550357 = 31550454
101 + 31550353 = 31550454
127 + 31550327 = 31550454
167 + 31550287 = 31550454

Showing the first eight; more decompositions exist.
