Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539348, here are decompositions:

11 + 31539337 = 31539348
17 + 31539331 = 31539348
19 + 31539329 = 31539348
59 + 31539289 = 31539348
107 + 31539241 = 31539348
157 + 31539191 = 31539348
397 + 31538951 = 31539348
461 + 31538887 = 31539348

Showing the first eight; more decompositions exist.
