Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467580, here are decompositions:

29 + 31467551 = 31467580
41 + 31467539 = 31467580
47 + 31467533 = 31467580
71 + 31467509 = 31467580
83 + 31467497 = 31467580
113 + 31467467 = 31467580
149 + 31467431 = 31467580
191 + 31467389 = 31467580

Showing the first eight; more decompositions exist.
