Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539602, here are decompositions:

19 + 31539583 = 31539602
79 + 31539523 = 31539602
103 + 31539499 = 31539602
163 + 31539439 = 31539602
181 + 31539421 = 31539602
271 + 31539331 = 31539602
313 + 31539289 = 31539602
331 + 31539271 = 31539602

Showing the first eight; more decompositions exist.
