Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490098, here are decompositions:

41 + 490057 = 490098
67 + 490031 = 490098
79 + 490019 = 490098
97 + 490001 = 490098
109 + 489989 = 490098
137 + 489961 = 490098
139 + 489959 = 490098
157 + 489941 = 490098

Showing the first eight; more decompositions exist.
