Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487242, here are decompositions:

23 + 487219 = 487242
29 + 487213 = 487242
31 + 487211 = 487242
59 + 487183 = 487242
109 + 487133 = 487242
131 + 487111 = 487242
149 + 487093 = 487242
163 + 487079 = 487242

Showing the first eight; more decompositions exist.
