Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538226, here are decompositions:

67 + 538159 = 538226
79 + 538147 = 538226
103 + 538123 = 538226
109 + 538117 = 538226
307 + 537919 = 538226
313 + 537913 = 538226
349 + 537877 = 538226
373 + 537853 = 538226

Showing the first eight; more decompositions exist.
