Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757444, here are decompositions:

67 + 8757377 = 8757444
71 + 8757373 = 8757444
103 + 8757341 = 8757444
167 + 8757277 = 8757444
181 + 8757263 = 8757444
191 + 8757253 = 8757444
257 + 8757187 = 8757444
271 + 8757173 = 8757444

Showing the first eight; more decompositions exist.
