Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549902, here are decompositions:

19 + 549883 = 549902
151 + 549751 = 549902
163 + 549739 = 549902
211 + 549691 = 549902
313 + 549589 = 549902
349 + 549553 = 549902
421 + 549481 = 549902
499 + 549403 = 549902

Showing the first eight; more decompositions exist.
