Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559348, here are decompositions:

31 + 31559317 = 31559348
97 + 31559251 = 31559348
109 + 31559239 = 31559348
199 + 31559149 = 31559348
277 + 31559071 = 31559348
409 + 31558939 = 31559348
421 + 31558927 = 31559348
577 + 31558771 = 31559348

Showing the first eight; more decompositions exist.
