Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523042, here are decompositions:

11 + 523031 = 523042
53 + 522989 = 523042
83 + 522959 = 523042
281 + 522761 = 523042
293 + 522749 = 523042
353 + 522689 = 523042
383 + 522659 = 523042
419 + 522623 = 523042

Showing the first eight; more decompositions exist.
