Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476546, here are decompositions:

29 + 31476517 = 31476546
37 + 31476509 = 31476546
47 + 31476499 = 31476546
89 + 31476457 = 31476546
97 + 31476449 = 31476546
109 + 31476437 = 31476546
113 + 31476433 = 31476546
163 + 31476383 = 31476546

Showing the first eight; more decompositions exist.
