Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488742, here are decompositions:

13 + 488729 = 488742
19 + 488723 = 488742
31 + 488711 = 488742
41 + 488701 = 488742
53 + 488689 = 488742
101 + 488641 = 488742
103 + 488639 = 488742
109 + 488633 = 488742

Showing the first eight; more decompositions exist.
