Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549722, here are decompositions:

3 + 549719 = 549722
31 + 549691 = 549722
73 + 549649 = 549722
79 + 549643 = 549722
211 + 549511 = 549722
241 + 549481 = 549722
331 + 549391 = 549722
409 + 549313 = 549722

Showing the first eight; more decompositions exist.
