Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757440, here are decompositions:

31 + 8757409 = 8757440
61 + 8757379 = 8757440
67 + 8757373 = 8757440
151 + 8757289 = 8757440
163 + 8757277 = 8757440
313 + 8757127 = 8757440
331 + 8757109 = 8757440
379 + 8757061 = 8757440

Showing the first eight; more decompositions exist.
