Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29900, here are decompositions:
- 19 + 29881 = 29900
- 37 + 29863 = 29900
- 67 + 29833 = 29900
- 97 + 29803 = 29900
- 139 + 29761 = 29900
- 229 + 29671 = 29900
- 271 + 29629 = 29900
- 313 + 29587 = 29900
Showing the first eight; more decompositions exist.
