Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623046, here are decompositions:

5 + 31623041 = 31623046
23 + 31623023 = 31623046
107 + 31622939 = 31623046
113 + 31622933 = 31623046
269 + 31622777 = 31623046
317 + 31622729 = 31623046
347 + 31622699 = 31623046
353 + 31622693 = 31623046

Showing the first eight; more decompositions exist.
