Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468136, here are decompositions:

109 + 31468027 = 31468136
199 + 31467937 = 31468136
283 + 31467853 = 31468136
307 + 31467829 = 31468136
373 + 31467763 = 31468136
409 + 31467727 = 31468136
547 + 31467589 = 31468136
577 + 31467559 = 31468136

Showing the first eight; more decompositions exist.
