Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467534, here are decompositions:

31 + 31467503 = 31467534
37 + 31467497 = 31467534
53 + 31467481 = 31467534
67 + 31467467 = 31467534
97 + 31467437 = 31467534
101 + 31467433 = 31467534
103 + 31467431 = 31467534
167 + 31467367 = 31467534

Showing the first eight; more decompositions exist.
