Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80530, here are decompositions:

3 + 80527 = 80530
17 + 80513 = 80530
41 + 80489 = 80530
59 + 80471 = 80530
83 + 80447 = 80530
101 + 80429 = 80530
167 + 80363 = 80530
251 + 80279 = 80530

Showing the first eight; more decompositions exist.
