Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523524, here are decompositions:

3 + 31523521 = 31523524
47 + 31523477 = 31523524
83 + 31523441 = 31523524
113 + 31523411 = 31523524
257 + 31523267 = 31523524
281 + 31523243 = 31523524
293 + 31523231 = 31523524
317 + 31523207 = 31523524

Showing the first eight; more decompositions exist.
