Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488642, here are decompositions:

3 + 488639 = 488642
31 + 488611 = 488642
103 + 488539 = 488642
139 + 488503 = 488642
223 + 488419 = 488642
241 + 488401 = 488642
313 + 488329 = 488642
331 + 488311 = 488642

Showing the first eight; more decompositions exist.
