Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466750, here are decompositions:

19 + 31466731 = 31466750
31 + 31466719 = 31466750
37 + 31466713 = 31466750
43 + 31466707 = 31466750
61 + 31466689 = 31466750
79 + 31466671 = 31466750
163 + 31466587 = 31466750
349 + 31466401 = 31466750

Showing the first eight; more decompositions exist.
