Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539092, here are decompositions:

3 + 31539089 = 31539092
19 + 31539073 = 31539092
31 + 31539061 = 31539092
313 + 31538779 = 31539092
349 + 31538743 = 31539092
373 + 31538719 = 31539092
379 + 31538713 = 31539092
421 + 31538671 = 31539092

Showing the first eight; more decompositions exist.
