Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539546, here are decompositions:

23 + 31539523 = 31539546
47 + 31539499 = 31539546
79 + 31539467 = 31539546
107 + 31539439 = 31539546
179 + 31539367 = 31539546
193 + 31539353 = 31539546
197 + 31539349 = 31539546
257 + 31539289 = 31539546

Showing the first eight; more decompositions exist.
