Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620524, here are decompositions:

131 + 8620393 = 8620524
163 + 8620361 = 8620524
197 + 8620327 = 8620524
257 + 8620267 = 8620524
293 + 8620231 = 8620524
307 + 8620217 = 8620524
313 + 8620211 = 8620524
337 + 8620187 = 8620524

Showing the first eight; more decompositions exist.
