Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623052, here are decompositions:

5 + 31623047 = 31623052
11 + 31623041 = 31623052
29 + 31623023 = 31623052
101 + 31622951 = 31623052
113 + 31622939 = 31623052
311 + 31622741 = 31623052
353 + 31622699 = 31623052
359 + 31622693 = 31623052

Showing the first eight; more decompositions exist.
