Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559768, here are decompositions:

109 + 31559659 = 31559768
127 + 31559641 = 31559768
367 + 31559401 = 31559768
397 + 31559371 = 31559768
607 + 31559161 = 31559768
619 + 31559149 = 31559768
811 + 31558957 = 31559768
829 + 31558939 = 31559768

Showing the first eight; more decompositions exist.
