Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701778, here are decompositions:

31 + 8701747 = 8701778
37 + 8701741 = 8701778
157 + 8701621 = 8701778
271 + 8701507 = 8701778
331 + 8701447 = 8701778
457 + 8701321 = 8701778
499 + 8701279 = 8701778
571 + 8701207 = 8701778

Showing the first eight; more decompositions exist.
