Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479680, here are decompositions:

41 + 479639 = 479680
137 + 479543 = 479680
167 + 479513 = 479680
191 + 479489 = 479680
239 + 479441 = 479680
251 + 479429 = 479680
293 + 479387 = 479680
353 + 479327 = 479680

Showing the first eight; more decompositions exist.
