Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466744, here are decompositions:

13 + 31466731 = 31466744
31 + 31466713 = 31466744
37 + 31466707 = 31466744
73 + 31466671 = 31466744
157 + 31466587 = 31466744
181 + 31466563 = 31466744
241 + 31466503 = 31466744
457 + 31466287 = 31466744

Showing the first eight; more decompositions exist.
