Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473746, here are decompositions:

13 + 31473733 = 31473746
43 + 31473703 = 31473746
163 + 31473583 = 31473746
223 + 31473523 = 31473746
349 + 31473397 = 31473746
433 + 31473313 = 31473746
463 + 31473283 = 31473746
709 + 31473037 = 31473746

Showing the first eight; more decompositions exist.
