Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492388, here are decompositions:

11 + 492377 = 492388
89 + 492299 = 492388
107 + 492281 = 492388
131 + 492257 = 492388
137 + 492251 = 492388
311 + 492077 = 492388
359 + 492029 = 492388
419 + 491969 = 492388

Showing the first eight; more decompositions exist.
