Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548226, here are decompositions:

179 + 31548047 = 31548226
197 + 31548029 = 31548226
233 + 31547993 = 31548226
293 + 31547933 = 31548226
389 + 31547837 = 31548226
443 + 31547783 = 31548226
617 + 31547609 = 31548226
719 + 31547507 = 31548226

Showing the first eight; more decompositions exist.
