Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623076, here are decompositions:

29 + 31623047 = 31623076
53 + 31623023 = 31623076
137 + 31622939 = 31623076
239 + 31622837 = 31623076
347 + 31622729 = 31623076
383 + 31622693 = 31623076
389 + 31622687 = 31623076
557 + 31622519 = 31623076

Showing the first eight; more decompositions exist.
