Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623134, here are decompositions:

13 + 31623121 = 31623134
73 + 31623061 = 31623134
211 + 31622923 = 31623134
241 + 31622893 = 31623134
271 + 31622863 = 31623134
331 + 31622803 = 31623134
421 + 31622713 = 31623134
463 + 31622671 = 31623134

Showing the first eight; more decompositions exist.
