Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623054, here are decompositions:

7 + 31623047 = 31623054
13 + 31623041 = 31623054
31 + 31623023 = 31623054
103 + 31622951 = 31623054
107 + 31622947 = 31623054
131 + 31622923 = 31623054
173 + 31622881 = 31623054
191 + 31622863 = 31623054

Showing the first eight; more decompositions exist.
