Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473822, here are decompositions:

11 + 31473811 = 31473822
13 + 31473809 = 31473822
41 + 31473781 = 31473822
43 + 31473779 = 31473822
89 + 31473733 = 31473822
223 + 31473599 = 31473822
229 + 31473593 = 31473822
239 + 31473583 = 31473822

Showing the first eight; more decompositions exist.
