Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466902, here are decompositions:

3 + 31466899 = 31466902
29 + 31466873 = 31466902
53 + 31466849 = 31466902
149 + 31466753 = 31466902
353 + 31466549 = 31466902
521 + 31466381 = 31466902
653 + 31466249 = 31466902
839 + 31466063 = 31466902

Showing the first eight; more decompositions exist.
