Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493922, here are decompositions:

13 + 31493909 = 31493922
23 + 31493899 = 31493922
41 + 31493881 = 31493922
71 + 31493851 = 31493922
101 + 31493821 = 31493922
139 + 31493783 = 31493922
179 + 31493743 = 31493922
211 + 31493711 = 31493922

Showing the first eight; more decompositions exist.
