Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29072, here are decompositions:
- 13 + 29059 = 29072
- 139 + 28933 = 29072
- 151 + 28921 = 29072
- 163 + 28909 = 29072
- 193 + 28879 = 29072
- 229 + 28843 = 29072
- 283 + 28789 = 29072
- 313 + 28759 = 29072
Showing the first eight; more decompositions exist.
