Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158480, here are decompositions:

31 + 158449 = 158480
37 + 158443 = 158480
61 + 158419 = 158480
73 + 158407 = 158480
109 + 158371 = 158480
139 + 158341 = 158480
151 + 158329 = 158480
211 + 158269 = 158480

Showing the first eight; more decompositions exist.
