Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473726, here are decompositions:

19 + 31473707 = 31473726
23 + 31473703 = 31473726
127 + 31473599 = 31473726
197 + 31473529 = 31473726
239 + 31473487 = 31473726
269 + 31473457 = 31473726
313 + 31473413 = 31473726
367 + 31473359 = 31473726

Showing the first eight; more decompositions exist.
