Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707808, here are decompositions:

61 + 8707747 = 8707808
97 + 8707711 = 8707808
139 + 8707669 = 8707808
157 + 8707651 = 8707808
229 + 8707579 = 8707808
271 + 8707537 = 8707808
331 + 8707477 = 8707808
379 + 8707429 = 8707808

Showing the first eight; more decompositions exist.
