Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467048, here are decompositions:

37 + 31467011 = 31467048
59 + 31466989 = 31467048
71 + 31466977 = 31467048
79 + 31466969 = 31467048
97 + 31466951 = 31467048
149 + 31466899 = 31467048
181 + 31466867 = 31467048
191 + 31466857 = 31467048

Showing the first eight; more decompositions exist.
