Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29146, here are decompositions:
- 17 + 29129 = 29146
- 23 + 29123 = 29146
- 83 + 29063 = 29146
- 113 + 29033 = 29146
- 137 + 29009 = 29146
- 167 + 28979 = 29146
- 197 + 28949 = 29146
- 353 + 28793 = 29146
Showing the first eight; more decompositions exist.
