Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623154, here are decompositions:

41 + 31623113 = 31623154
107 + 31623047 = 31623154
113 + 31623041 = 31623154
131 + 31623023 = 31623154
317 + 31622837 = 31623154
461 + 31622693 = 31623154
467 + 31622687 = 31623154
491 + 31622663 = 31623154

Showing the first eight; more decompositions exist.
