Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548780, here are decompositions:

19 + 548761 = 548780
31 + 548749 = 548780
61 + 548719 = 548780
73 + 548707 = 548780
103 + 548677 = 548780
109 + 548671 = 548780
151 + 548629 = 548780
157 + 548623 = 548780

Showing the first eight; more decompositions exist.
