Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29972, here are decompositions:
- 13 + 29959 = 29972
- 109 + 29863 = 29972
- 139 + 29833 = 29972
- 211 + 29761 = 29972
- 331 + 29641 = 29972
- 373 + 29599 = 29972
- 499 + 29473 = 29972
- 571 + 29401 = 29972
Showing the first eight; more decompositions exist.
