Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 544240, here are decompositions:

17 + 544223 = 544240
41 + 544199 = 544240
101 + 544139 = 544240
107 + 544133 = 544240
131 + 544109 = 544240
227 + 544013 = 544240
233 + 544007 = 544240
239 + 544001 = 544240

Showing the first eight; more decompositions exist.
