Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506226, here are decompositions:

53 + 31506173 = 31506226
107 + 31506119 = 31506226
197 + 31506029 = 31506226
233 + 31505993 = 31506226
317 + 31505909 = 31506226
383 + 31505843 = 31506226
419 + 31505807 = 31506226
443 + 31505783 = 31506226

Showing the first eight; more decompositions exist.
