Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179442, here are decompositions:

5 + 179437 = 179442
13 + 179429 = 179442
31 + 179411 = 179442
59 + 179383 = 179442
61 + 179381 = 179442
73 + 179369 = 179442
173 + 179269 = 179442
181 + 179261 = 179442

Showing the first eight; more decompositions exist.
