Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294961666, here are decompositions:
- 3 + 4294961663 = 4294961666
- 43 + 4294961623 = 4294961666
- 139 + 4294961527 = 4294961666
- 199 + 4294961467 = 4294961666
- 313 + 4294961353 = 4294961666
- 349 + 4294961317 = 4294961666
- 379 + 4294961287 = 4294961666
- 487 + 4294961179 = 4294961666
Showing the first eight; more decompositions exist.
