Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466792, here are decompositions:

43 + 31466749 = 31466792
61 + 31466731 = 31466792
73 + 31466719 = 31466792
79 + 31466713 = 31466792
103 + 31466689 = 31466792
163 + 31466629 = 31466792
229 + 31466563 = 31466792
463 + 31466329 = 31466792

Showing the first eight; more decompositions exist.
