Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498158, here are decompositions:

97 + 498061 = 498158
181 + 497977 = 498158
229 + 497929 = 498158
307 + 497851 = 498158
421 + 497737 = 498158
439 + 497719 = 498158
457 + 497701 = 498158
487 + 497671 = 498158

Showing the first eight; more decompositions exist.
