Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476570, here are decompositions:

19 + 31476551 = 31476570
23 + 31476547 = 31476570
53 + 31476517 = 31476570
61 + 31476509 = 31476570
71 + 31476499 = 31476570
109 + 31476461 = 31476570
113 + 31476457 = 31476570
137 + 31476433 = 31476570

Showing the first eight; more decompositions exist.
