Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29840, here are decompositions:
- 3 + 29837 = 29840
- 7 + 29833 = 29840
- 37 + 29803 = 29840
- 79 + 29761 = 29840
- 157 + 29683 = 29840
- 199 + 29641 = 29840
- 211 + 29629 = 29840
- 229 + 29611 = 29840
Showing the first eight; more decompositions exist.
