Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538148, here are decompositions:

31 + 538117 = 538148
97 + 538051 = 538148
157 + 537991 = 538148
229 + 537919 = 538148
271 + 537877 = 538148
307 + 537841 = 538148
337 + 537811 = 538148
367 + 537781 = 538148

Showing the first eight; more decompositions exist.
