Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561226, here are decompositions:

53 + 561173 = 561226
167 + 561059 = 561226
173 + 561053 = 561226
179 + 561047 = 561226
257 + 560969 = 561226
353 + 560873 = 561226
389 + 560837 = 561226
443 + 560783 = 561226

Showing the first eight; more decompositions exist.
