Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758178, here are decompositions:

7 + 8758171 = 8758178
61 + 8758117 = 8758178
97 + 8758081 = 8758178
349 + 8757829 = 8758178
379 + 8757799 = 8758178
409 + 8757769 = 8758178
421 + 8757757 = 8758178
487 + 8757691 = 8758178

Showing the first eight; more decompositions exist.
