Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702288, here are decompositions:

37 + 8702251 = 8702288
109 + 8702179 = 8702288
139 + 8702149 = 8702288
151 + 8702137 = 8702288
157 + 8702131 = 8702288
181 + 8702107 = 8702288
337 + 8701951 = 8702288
367 + 8701921 = 8702288

Showing the first eight; more decompositions exist.
