Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548642, here are decompositions:

13 + 548629 = 548642
19 + 548623 = 548642
109 + 548533 = 548642
139 + 548503 = 548642
181 + 548461 = 548642
271 + 548371 = 548642
379 + 548263 = 548642
421 + 548221 = 548642

Showing the first eight; more decompositions exist.
