Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29140, here are decompositions:
- 3 + 29137 = 29140
- 11 + 29129 = 29140
- 17 + 29123 = 29140
- 107 + 29033 = 29140
- 113 + 29027 = 29140
- 131 + 29009 = 29140
- 179 + 28961 = 29140
- 191 + 28949 = 29140
Showing the first eight; more decompositions exist.
