Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29112, here are decompositions:
- 11 + 29101 = 29112
- 53 + 29059 = 29112
- 79 + 29033 = 29112
- 89 + 29023 = 29112
- 103 + 29009 = 29112
- 151 + 28961 = 29112
- 163 + 28949 = 29112
- 179 + 28933 = 29112
Showing the first eight; more decompositions exist.
