Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481418, here are decompositions:

31 + 481387 = 481418
211 + 481207 = 481418
241 + 481177 = 481418
271 + 481147 = 481418
277 + 481141 = 481418
331 + 481087 = 481418
367 + 481051 = 481418
397 + 481021 = 481418

Showing the first eight; more decompositions exist.
