Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164442, here are decompositions:

11 + 164431 = 164442
13 + 164429 = 164442
23 + 164419 = 164442
29 + 164413 = 164442
71 + 164371 = 164442
79 + 164363 = 164442
101 + 164341 = 164442
151 + 164291 = 164442

Showing the first eight; more decompositions exist.
