Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473760, here are decompositions:

53 + 31473707 = 31473760
167 + 31473593 = 31473760
179 + 31473581 = 31473760
281 + 31473479 = 31473760
347 + 31473413 = 31473760
401 + 31473359 = 31473760
509 + 31473251 = 31473760
557 + 31473203 = 31473760

Showing the first eight; more decompositions exist.
