Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563068, here are decompositions:

37 + 31563031 = 31563068
67 + 31563001 = 31563068
109 + 31562959 = 31563068
151 + 31562917 = 31563068
157 + 31562911 = 31563068
241 + 31562827 = 31563068
331 + 31562737 = 31563068
457 + 31562611 = 31563068

Showing the first eight; more decompositions exist.
