Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472642, here are decompositions:

3 + 472639 = 472642
11 + 472631 = 472642
83 + 472559 = 472642
101 + 472541 = 472642
173 + 472469 = 472642
251 + 472391 = 472642
293 + 472349 = 472642
311 + 472331 = 472642

Showing the first eight; more decompositions exist.
