Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708840, here are decompositions:

37 + 8708803 = 8708840
109 + 8708731 = 8708840
139 + 8708701 = 8708840
223 + 8708617 = 8708840
229 + 8708611 = 8708840
313 + 8708527 = 8708840
331 + 8708509 = 8708840
379 + 8708461 = 8708840

Showing the first eight; more decompositions exist.
