Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485346, here are decompositions:

5 + 31485341 = 31485346
149 + 31485197 = 31485346
239 + 31485107 = 31485346
353 + 31484993 = 31485346
443 + 31484903 = 31485346
509 + 31484837 = 31485346
569 + 31484777 = 31485346
593 + 31484753 = 31485346

Showing the first eight; more decompositions exist.
