Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546792, here are decompositions:

3 + 31546789 = 31546792
71 + 31546721 = 31546792
83 + 31546709 = 31546792
131 + 31546661 = 31546792
191 + 31546601 = 31546792
239 + 31546553 = 31546792
443 + 31546349 = 31546792
491 + 31546301 = 31546792

Showing the first eight; more decompositions exist.
