Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668472, here are decompositions:
- 13 + 8668459 = 8668472
- 103 + 8668369 = 8668472
- 193 + 8668279 = 8668472
- 199 + 8668273 = 8668472
- 271 + 8668201 = 8668472
- 331 + 8668141 = 8668472
- 409 + 8668063 = 8668472
- 499 + 8667973 = 8668472
Showing the first eight; more decompositions exist.
