Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466754, here are decompositions:

5 + 31466749 = 31466754
23 + 31466731 = 31466754
41 + 31466713 = 31466754
47 + 31466707 = 31466754
61 + 31466693 = 31466754
83 + 31466671 = 31466754
97 + 31466657 = 31466754
127 + 31466627 = 31466754

Showing the first eight; more decompositions exist.
