Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523754, here are decompositions:

5 + 31523749 = 31523754
47 + 31523707 = 31523754
103 + 31523651 = 31523754
107 + 31523647 = 31523754
233 + 31523521 = 31523754
277 + 31523477 = 31523754
281 + 31523473 = 31523754
293 + 31523461 = 31523754

Showing the first eight; more decompositions exist.
