Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488618, here are decompositions:

7 + 488611 = 488618
79 + 488539 = 488618
199 + 488419 = 488618
211 + 488407 = 488618
271 + 488347 = 488618
307 + 488311 = 488618
331 + 488287 = 488618
379 + 488239 = 488618

Showing the first eight; more decompositions exist.
