Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179436, here are decompositions:

7 + 179429 = 179436
29 + 179407 = 179436
43 + 179393 = 179436
53 + 179383 = 179436
67 + 179369 = 179436
79 + 179357 = 179436
109 + 179327 = 179436
149 + 179287 = 179436

Showing the first eight; more decompositions exist.
