Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476510, here are decompositions:

11 + 31476499 = 31476510
53 + 31476457 = 31476510
59 + 31476451 = 31476510
61 + 31476449 = 31476510
73 + 31476437 = 31476510
97 + 31476413 = 31476510
127 + 31476383 = 31476510
137 + 31476373 = 31476510

Showing the first eight; more decompositions exist.
