Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8703778, here are decompositions:

59 + 8703719 = 8703778
137 + 8703641 = 8703778
197 + 8703581 = 8703778
227 + 8703551 = 8703778
389 + 8703389 = 8703778
401 + 8703377 = 8703778
431 + 8703347 = 8703778
491 + 8703287 = 8703778

Showing the first eight; more decompositions exist.
