Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492438, here are decompositions:

7 + 492431 = 492438
17 + 492421 = 492438
29 + 492409 = 492438
41 + 492397 = 492438
61 + 492377 = 492438
139 + 492299 = 492438
157 + 492281 = 492438
181 + 492257 = 492438

Showing the first eight; more decompositions exist.
