Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158490, here are decompositions:

41 + 158449 = 158490
47 + 158443 = 158490
61 + 158429 = 158490
71 + 158419 = 158490
83 + 158407 = 158490
97 + 158393 = 158490
127 + 158363 = 158490
131 + 158359 = 158490

Showing the first eight; more decompositions exist.
