Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473524, here are decompositions:

37 + 31473487 = 31473524
67 + 31473457 = 31473524
127 + 31473397 = 31473524
193 + 31473331 = 31473524
211 + 31473313 = 31473524
241 + 31473283 = 31473524
283 + 31473241 = 31473524
307 + 31473217 = 31473524

Showing the first eight; more decompositions exist.
