Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720462, here are decompositions:

31 + 8720431 = 8720462
73 + 8720389 = 8720462
151 + 8720311 = 8720462
181 + 8720281 = 8720462
229 + 8720233 = 8720462
271 + 8720191 = 8720462
349 + 8720113 = 8720462
463 + 8719999 = 8720462

Showing the first eight; more decompositions exist.
