Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563110, here are decompositions:

37 + 31563073 = 31563110
67 + 31563043 = 31563110
79 + 31563031 = 31563110
97 + 31563013 = 31563110
109 + 31563001 = 31563110
127 + 31562983 = 31563110
151 + 31562959 = 31563110
193 + 31562917 = 31563110

Showing the first eight; more decompositions exist.
