Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623146, here are decompositions:

199 + 31622947 = 31623146
223 + 31622923 = 31623146
283 + 31622863 = 31623146
337 + 31622809 = 31623146
367 + 31622779 = 31623146
433 + 31622713 = 31623146
463 + 31622683 = 31623146
547 + 31622599 = 31623146

Showing the first eight; more decompositions exist.
