Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726340, here are decompositions:
- 11 + 8726329 = 8726340
- 17 + 8726323 = 8726340
- 67 + 8726273 = 8726340
- 83 + 8726257 = 8726340
- 97 + 8726243 = 8726340
- 101 + 8726239 = 8726340
- 113 + 8726227 = 8726340
- 131 + 8726209 = 8726340
Showing the first eight; more decompositions exist.
