Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563050, here are decompositions:

7 + 31563043 = 31563050
19 + 31563031 = 31563050
37 + 31563013 = 31563050
67 + 31562983 = 31563050
139 + 31562911 = 31563050
223 + 31562827 = 31563050
271 + 31562779 = 31563050
283 + 31562767 = 31563050

Showing the first eight; more decompositions exist.
