Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538186, here are decompositions:

23 + 538163 = 538186
29 + 538157 = 538186
59 + 538127 = 538186
107 + 538079 = 538186
113 + 538073 = 538186
137 + 538049 = 538186
167 + 538019 = 538186
443 + 537743 = 538186

Showing the first eight; more decompositions exist.
