Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484670, here are decompositions:

23 + 31484647 = 31484670
43 + 31484627 = 31484670
53 + 31484617 = 31484670
101 + 31484569 = 31484670
127 + 31484543 = 31484670
137 + 31484533 = 31484670
157 + 31484513 = 31484670
167 + 31484503 = 31484670

Showing the first eight; more decompositions exist.
