Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185138, here are decompositions:

7 + 185131 = 185138
61 + 185077 = 185138
67 + 185071 = 185138
139 + 184999 = 185138
181 + 184957 = 185138
307 + 184831 = 185138
487 + 184651 = 185138
571 + 184567 = 185138

Showing the first eight; more decompositions exist.
