Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 485442, here are decompositions:

5 + 485437 = 485442
19 + 485423 = 485442
31 + 485411 = 485442
53 + 485389 = 485442
59 + 485383 = 485442
71 + 485371 = 485442
79 + 485363 = 485442
131 + 485311 = 485442

Showing the first eight; more decompositions exist.
