Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473502, here are decompositions:

23 + 31473479 = 31473502
89 + 31473413 = 31473502
239 + 31473263 = 31473502
251 + 31473251 = 31473502
293 + 31473209 = 31473502
311 + 31473191 = 31473502
419 + 31473083 = 31473502
461 + 31473041 = 31473502

Showing the first eight; more decompositions exist.
