Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539596, here are decompositions:

3 + 31539593 = 31539596
13 + 31539583 = 31539596
73 + 31539523 = 31539596
97 + 31539499 = 31539596
157 + 31539439 = 31539596
229 + 31539367 = 31539596
307 + 31539289 = 31539596
313 + 31539283 = 31539596

Showing the first eight; more decompositions exist.
