Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49020, here are decompositions:

11 + 49009 = 49020
17 + 49003 = 49020
29 + 48991 = 49020
31 + 48989 = 49020
47 + 48973 = 49020
67 + 48953 = 49020
73 + 48947 = 49020
113 + 48907 = 49020

Showing the first eight; more decompositions exist.
