Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466894, here are decompositions:

37 + 31466857 = 31466894
73 + 31466821 = 31466894
103 + 31466791 = 31466894
163 + 31466731 = 31466894
181 + 31466713 = 31466894
223 + 31466671 = 31466894
307 + 31466587 = 31466894
331 + 31466563 = 31466894

Showing the first eight; more decompositions exist.
