Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487226, here are decompositions:

7 + 487219 = 487226
13 + 487213 = 487226
43 + 487183 = 487226
127 + 487099 = 487226
277 + 486949 = 487226
283 + 486943 = 487226
409 + 486817 = 487226
457 + 486769 = 487226

Showing the first eight; more decompositions exist.
