Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488738, here are decompositions:

37 + 488701 = 488738
97 + 488641 = 488738
127 + 488611 = 488738
199 + 488539 = 488738
331 + 488407 = 488738
337 + 488401 = 488738
409 + 488329 = 488738
421 + 488317 = 488738

Showing the first eight; more decompositions exist.
