Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158528, here are decompositions:

79 + 158449 = 158528
109 + 158419 = 158528
157 + 158371 = 158528
199 + 158329 = 158528
367 + 158161 = 158528
457 + 158071 = 158528
499 + 158029 = 158528
577 + 157951 = 158528

Showing the first eight; more decompositions exist.
