Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750390, here are decompositions:

3 + 8750387 = 8750390
13 + 8750377 = 8750390
43 + 8750347 = 8750390
97 + 8750293 = 8750390
151 + 8750239 = 8750390
157 + 8750233 = 8750390
163 + 8750227 = 8750390
193 + 8750197 = 8750390

Showing the first eight; more decompositions exist.
