Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473634, here are decompositions:

41 + 31473593 = 31473634
53 + 31473581 = 31473634
197 + 31473437 = 31473634
383 + 31473251 = 31473634
431 + 31473203 = 31473634
443 + 31473191 = 31473634
461 + 31473173 = 31473634
557 + 31473077 = 31473634

Showing the first eight; more decompositions exist.
