Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466984, here are decompositions:

7 + 31466977 = 31466984
127 + 31466857 = 31466984
163 + 31466821 = 31466984
193 + 31466791 = 31466984
271 + 31466713 = 31466984
277 + 31466707 = 31466984
313 + 31466671 = 31466984
397 + 31466587 = 31466984

Showing the first eight; more decompositions exist.
