Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708778, here are decompositions:

37 + 8708741 = 8708778
47 + 8708731 = 8708778
61 + 8708717 = 8708778
139 + 8708639 = 8708778
151 + 8708627 = 8708778
157 + 8708621 = 8708778
167 + 8708611 = 8708778
241 + 8708537 = 8708778

Showing the first eight; more decompositions exist.
