Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538244, here are decompositions:

43 + 538201 = 538244
97 + 538147 = 538244
127 + 538117 = 538244
151 + 538093 = 538244
193 + 538051 = 538244
331 + 537913 = 538244
367 + 537877 = 538244
397 + 537847 = 538244

Showing the first eight; more decompositions exist.
