Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657474, here are decompositions:

13 + 8657461 = 8657474
43 + 8657431 = 8657474
97 + 8657377 = 8657474
151 + 8657323 = 8657474
313 + 8657161 = 8657474
421 + 8657053 = 8657474
433 + 8657041 = 8657474
457 + 8657017 = 8657474

Showing the first eight; more decompositions exist.
