Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158430, here are decompositions:

11 + 158419 = 158430
23 + 158407 = 158430
37 + 158393 = 158430
59 + 158371 = 158430
67 + 158363 = 158430
71 + 158359 = 158430
73 + 158357 = 158430
79 + 158351 = 158430

Showing the first eight; more decompositions exist.
