Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1210, here are decompositions:
- 17 + 1193 = 1210
- 23 + 1187 = 1210
- 29 + 1181 = 1210
- 47 + 1163 = 1210
- 59 + 1151 = 1210
- 101 + 1109 = 1210
- 107 + 1103 = 1210
- 113 + 1097 = 1210
Showing the first eight; more decompositions exist.
