Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483772, here are decompositions:

13 + 31483759 = 31483772
109 + 31483663 = 31483772
223 + 31483549 = 31483772
421 + 31483351 = 31483772
769 + 31483003 = 31483772
883 + 31482889 = 31483772
1063 + 31482709 = 31483772
1129 + 31482643 = 31483772

Showing the first eight; more decompositions exist.
