Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487942, here are decompositions:

53 + 487889 = 487942
113 + 487829 = 487942
131 + 487811 = 487942
149 + 487793 = 487942
173 + 487769 = 487942
233 + 487709 = 487942
239 + 487703 = 487942
251 + 487691 = 487942

Showing the first eight; more decompositions exist.
