Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681264, here are decompositions:

13 + 8681251 = 8681264
43 + 8681221 = 8681264
73 + 8681191 = 8681264
271 + 8680993 = 8681264
313 + 8680951 = 8681264
463 + 8680801 = 8681264
523 + 8680741 = 8681264
541 + 8680723 = 8681264

Showing the first eight; more decompositions exist.
