Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473748, here are decompositions:

41 + 31473707 = 31473748
149 + 31473599 = 31473748
167 + 31473581 = 31473748
269 + 31473479 = 31473748
311 + 31473437 = 31473748
389 + 31473359 = 31473748
557 + 31473191 = 31473748
587 + 31473161 = 31473748

Showing the first eight; more decompositions exist.
