Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551454, here are decompositions:

3 + 31551451 = 31551454
17 + 31551437 = 31551454
23 + 31551431 = 31551454
41 + 31551413 = 31551454
47 + 31551407 = 31551454
101 + 31551353 = 31551454
107 + 31551347 = 31551454
113 + 31551341 = 31551454

Showing the first eight; more decompositions exist.
