Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701478, here are decompositions:

31 + 8701447 = 8701478
157 + 8701321 = 8701478
199 + 8701279 = 8701478
211 + 8701267 = 8701478
271 + 8701207 = 8701478
337 + 8701141 = 8701478
397 + 8701081 = 8701478
421 + 8701057 = 8701478

Showing the first eight; more decompositions exist.
