Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539426, here are decompositions:

5 + 31539421 = 31539426
13 + 31539413 = 31539426
59 + 31539367 = 31539426
73 + 31539353 = 31539426
89 + 31539337 = 31539426
97 + 31539329 = 31539426
137 + 31539289 = 31539426
197 + 31539229 = 31539426

Showing the first eight; more decompositions exist.
