Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680742, here are decompositions:

19 + 8680723 = 8680742
43 + 8680699 = 8680742
73 + 8680669 = 8680742
199 + 8680543 = 8680742
229 + 8680513 = 8680742
241 + 8680501 = 8680742
271 + 8680471 = 8680742
373 + 8680369 = 8680742

Showing the first eight; more decompositions exist.
