Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488318, here are decompositions:

7 + 488311 = 488318
31 + 488287 = 488318
79 + 488239 = 488318
109 + 488209 = 488318
157 + 488161 = 488318
199 + 488119 = 488318
307 + 488011 = 488318
421 + 487897 = 488318

Showing the first eight; more decompositions exist.
