Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549642, here are decompositions:

19 + 549623 = 549642
53 + 549589 = 549642
73 + 549569 = 549642
89 + 549553 = 549642
109 + 549533 = 549642
131 + 549511 = 549642
139 + 549503 = 549642
193 + 549449 = 549642

Showing the first eight; more decompositions exist.
