Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466876, here are decompositions:

3 + 31466873 = 31466876
19 + 31466857 = 31466876
127 + 31466749 = 31466876
157 + 31466719 = 31466876
163 + 31466713 = 31466876
313 + 31466563 = 31466876
373 + 31466503 = 31466876
487 + 31466389 = 31466876

Showing the first eight; more decompositions exist.
