Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 536138, here are decompositions:

37 + 536101 = 536138
79 + 536059 = 536138
139 + 535999 = 536138
181 + 535957 = 536138
199 + 535939 = 536138
277 + 535861 = 536138
367 + 535771 = 536138
397 + 535741 = 536138

Showing the first eight; more decompositions exist.
