Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476456, here are decompositions:

5 + 31476451 = 31476456
7 + 31476449 = 31476456
19 + 31476437 = 31476456
23 + 31476433 = 31476456
43 + 31476413 = 31476456
73 + 31476383 = 31476456
83 + 31476373 = 31476456
103 + 31476353 = 31476456

Showing the first eight; more decompositions exist.
