Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15038, here are decompositions:
- 7 + 15031 = 15038
- 109 + 14929 = 15038
- 151 + 14887 = 15038
- 211 + 14827 = 15038
- 241 + 14797 = 15038
- 271 + 14767 = 15038
- 307 + 14731 = 15038
- 409 + 14629 = 15038
Showing the first eight; more decompositions exist.
