Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691524, here are decompositions:

43 + 8691481 = 8691524
73 + 8691451 = 8691524
151 + 8691373 = 8691524
157 + 8691367 = 8691524
211 + 8691313 = 8691524
277 + 8691247 = 8691524
313 + 8691211 = 8691524
337 + 8691187 = 8691524

Showing the first eight; more decompositions exist.
