Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540158, here are decompositions:

19 + 540139 = 540158
37 + 540121 = 540158
79 + 540079 = 540158
97 + 540061 = 540158
211 + 539947 = 540158
277 + 539881 = 540158
397 + 539761 = 540158
709 + 539449 = 540158

Showing the first eight; more decompositions exist.
