Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155592, here are decompositions:

11 + 155581 = 155592
13 + 155579 = 155592
23 + 155569 = 155592
53 + 155539 = 155592
71 + 155521 = 155592
83 + 155509 = 155592
131 + 155461 = 155592
139 + 155453 = 155592

Showing the first eight; more decompositions exist.
