Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680242, here are decompositions:

13 + 8680229 = 8680242
23 + 8680219 = 8680242
29 + 8680213 = 8680242
41 + 8680201 = 8680242
71 + 8680171 = 8680242
89 + 8680153 = 8680242
139 + 8680103 = 8680242
199 + 8680043 = 8680242

Showing the first eight; more decompositions exist.
