Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29640, here are decompositions:
- 7 + 29633 = 29640
- 11 + 29629 = 29640
- 29 + 29611 = 29640
- 41 + 29599 = 29640
- 53 + 29587 = 29640
- 59 + 29581 = 29640
- 67 + 29573 = 29640
- 71 + 29569 = 29640
Showing the first eight; more decompositions exist.
