Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462736, here are decompositions:

7 + 31462729 = 31462736
13 + 31462723 = 31462736
127 + 31462609 = 31462736
157 + 31462579 = 31462736
163 + 31462573 = 31462736
229 + 31462507 = 31462736
373 + 31462363 = 31462736
379 + 31462357 = 31462736

Showing the first eight; more decompositions exist.
