Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538236, here are decompositions:

37 + 538199 = 538236
73 + 538163 = 538236
79 + 538157 = 538236
89 + 538147 = 538236
109 + 538127 = 538236
113 + 538123 = 538236
157 + 538079 = 538236
163 + 538073 = 538236

Showing the first eight; more decompositions exist.
