Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158502, here are decompositions:

13 + 158489 = 158502
53 + 158449 = 158502
59 + 158443 = 158502
73 + 158429 = 158502
83 + 158419 = 158502
109 + 158393 = 158502
131 + 158371 = 158502
139 + 158363 = 158502

Showing the first eight; more decompositions exist.
