Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757378, here are decompositions:

5 + 8757373 = 8757378
37 + 8757341 = 8757378
89 + 8757289 = 8757378
101 + 8757277 = 8757378
109 + 8757269 = 8757378
191 + 8757187 = 8757378
199 + 8757179 = 8757378
251 + 8757127 = 8757378

Showing the first eight; more decompositions exist.
