Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487136, here are decompositions:

3 + 487133 = 487136
37 + 487099 = 487136
43 + 487093 = 487136
79 + 487057 = 487136
193 + 486943 = 487136
229 + 486907 = 487136
367 + 486769 = 487136
379 + 486757 = 487136

Showing the first eight; more decompositions exist.
