Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467090, here are decompositions:

7 + 31467083 = 31467090
19 + 31467071 = 31467090
23 + 31467067 = 31467090
79 + 31467011 = 31467090
97 + 31466993 = 31467090
101 + 31466989 = 31467090
113 + 31466977 = 31467090
139 + 31466951 = 31467090

Showing the first eight; more decompositions exist.
