Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501478, here are decompositions:

59 + 501419 = 501478
137 + 501341 = 501478
179 + 501299 = 501478
191 + 501287 = 501478
269 + 501209 = 501478
281 + 501197 = 501478
347 + 501131 = 501478
389 + 501089 = 501478

Showing the first eight; more decompositions exist.
