Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473718, here are decompositions:

11 + 31473707 = 31473718
137 + 31473581 = 31473718
239 + 31473479 = 31473718
281 + 31473437 = 31473718
359 + 31473359 = 31473718
467 + 31473251 = 31473718
509 + 31473209 = 31473718
557 + 31473161 = 31473718

Showing the first eight; more decompositions exist.
