Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29720, here are decompositions:
- 3 + 29717 = 29720
- 37 + 29683 = 29720
- 79 + 29641 = 29720
- 109 + 29611 = 29720
- 139 + 29581 = 29720
- 151 + 29569 = 29720
- 193 + 29527 = 29720
- 277 + 29443 = 29720
Showing the first eight; more decompositions exist.
