Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29912, here are decompositions:
- 31 + 29881 = 29912
- 61 + 29851 = 29912
- 79 + 29833 = 29912
- 109 + 29803 = 29912
- 151 + 29761 = 29912
- 229 + 29683 = 29912
- 241 + 29671 = 29912
- 271 + 29641 = 29912
Showing the first eight; more decompositions exist.
