Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500442, here are decompositions:

11 + 500431 = 500442
29 + 500413 = 500442
53 + 500389 = 500442
73 + 500369 = 500442
79 + 500363 = 500442
101 + 500341 = 500442
109 + 500333 = 500442
193 + 500249 = 500442

Showing the first eight; more decompositions exist.
