Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490748, here are decompositions:

7 + 490741 = 490748
157 + 490591 = 490748
199 + 490549 = 490748
211 + 490537 = 490748
229 + 490519 = 490748
331 + 490417 = 490748
409 + 490339 = 490748
439 + 490309 = 490748

Showing the first eight; more decompositions exist.
