Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485226, here are decompositions:

5 + 31485221 = 31485226
29 + 31485197 = 31485226
167 + 31485059 = 31485226
233 + 31484993 = 31485226
389 + 31484837 = 31485226
449 + 31484777 = 31485226
599 + 31484627 = 31485226
683 + 31484543 = 31485226

Showing the first eight; more decompositions exist.
