Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467598, here are decompositions:

5 + 31467593 = 31467598
11 + 31467587 = 31467598
47 + 31467551 = 31467598
59 + 31467539 = 31467598
89 + 31467509 = 31467598
101 + 31467497 = 31467598
131 + 31467467 = 31467598
167 + 31467431 = 31467598

Showing the first eight; more decompositions exist.
