Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563062, here are decompositions:

19 + 31563043 = 31563062
31 + 31563031 = 31563062
61 + 31563001 = 31563062
79 + 31562983 = 31563062
103 + 31562959 = 31563062
151 + 31562911 = 31563062
283 + 31562779 = 31563062
379 + 31562683 = 31563062

Showing the first eight; more decompositions exist.
