Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29990, here are decompositions:
- 7 + 29983 = 29990
- 31 + 29959 = 29990
- 43 + 29947 = 29990
- 73 + 29917 = 29990
- 109 + 29881 = 29990
- 127 + 29863 = 29990
- 139 + 29851 = 29990
- 157 + 29833 = 29990
Showing the first eight; more decompositions exist.
