Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492144, here are decompositions:

31 + 492113 = 492144
41 + 492103 = 492144
61 + 492083 = 492144
67 + 492077 = 492144
83 + 492061 = 492144
97 + 492047 = 492144
127 + 492017 = 492144
131 + 492013 = 492144

Showing the first eight; more decompositions exist.
