Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548690, here are decompositions:

3 + 548687 = 548690
13 + 548677 = 548690
19 + 548671 = 548690
61 + 548629 = 548690
67 + 548623 = 548690
157 + 548533 = 548690
229 + 548461 = 548690
283 + 548407 = 548690

Showing the first eight; more decompositions exist.
