Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467620, here are decompositions:

31 + 31467589 = 31467620
61 + 31467559 = 31467620
139 + 31467481 = 31467620
421 + 31467199 = 31467620
439 + 31467181 = 31467620
463 + 31467157 = 31467620
487 + 31467133 = 31467620
631 + 31466989 = 31467620

Showing the first eight; more decompositions exist.
