Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155048, here are decompositions:

31 + 155017 = 155048
67 + 154981 = 155048
151 + 154897 = 155048
199 + 154849 = 155048
241 + 154807 = 155048
349 + 154699 = 155048
367 + 154681 = 155048
379 + 154669 = 155048

Showing the first eight; more decompositions exist.
