Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549860, here are decompositions:

43 + 549817 = 549860
109 + 549751 = 549860
127 + 549733 = 549860
193 + 549667 = 549860
211 + 549649 = 549860
271 + 549589 = 549860
307 + 549553 = 549860
313 + 549547 = 549860

Showing the first eight; more decompositions exist.
