Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668438, here are decompositions:
- 17 + 8668421 = 8668438
- 59 + 8668379 = 8668438
- 71 + 8668367 = 8668438
- 89 + 8668349 = 8668438
- 137 + 8668301 = 8668438
- 281 + 8668157 = 8668438
- 509 + 8667929 = 8668438
- 617 + 8667821 = 8668438
Showing the first eight; more decompositions exist.
