Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481286, here are decompositions:

37 + 481249 = 481286
79 + 481207 = 481286
109 + 481177 = 481286
139 + 481147 = 481286
163 + 481123 = 481286
193 + 481093 = 481286
199 + 481087 = 481286
277 + 481009 = 481286

Showing the first eight; more decompositions exist.
