Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158550, here are decompositions:

13 + 158537 = 158550
23 + 158527 = 158550
31 + 158519 = 158550
43 + 158507 = 158550
61 + 158489 = 158550
101 + 158449 = 158550
107 + 158443 = 158550
131 + 158419 = 158550

Showing the first eight; more decompositions exist.
