Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29440, here are decompositions:
- 3 + 29437 = 29440
- 11 + 29429 = 29440
- 17 + 29423 = 29440
- 29 + 29411 = 29440
- 41 + 29399 = 29440
- 53 + 29387 = 29440
- 101 + 29339 = 29440
- 107 + 29333 = 29440
Showing the first eight; more decompositions exist.
