Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 544138, here are decompositions:

5 + 544133 = 544138
29 + 544109 = 544138
41 + 544097 = 544138
107 + 544031 = 544138
131 + 544007 = 544138
137 + 544001 = 544138
167 + 543971 = 544138
227 + 543911 = 544138

Showing the first eight; more decompositions exist.
