Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476728, here are decompositions:

37 + 31476691 = 31476728
97 + 31476631 = 31476728
181 + 31476547 = 31476728
211 + 31476517 = 31476728
229 + 31476499 = 31476728
271 + 31476457 = 31476728
277 + 31476451 = 31476728
337 + 31476391 = 31476728

Showing the first eight; more decompositions exist.
