Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155768, here are decompositions:

37 + 155731 = 155768
61 + 155707 = 155768
79 + 155689 = 155768
97 + 155671 = 155768
199 + 155569 = 155768
211 + 155557 = 155768
229 + 155539 = 155768
307 + 155461 = 155768

Showing the first eight; more decompositions exist.
