Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1252, here are decompositions:
- 3 + 1249 = 1252
- 23 + 1229 = 1252
- 29 + 1223 = 1252
- 59 + 1193 = 1252
- 71 + 1181 = 1252
- 89 + 1163 = 1252
- 101 + 1151 = 1252
- 149 + 1103 = 1252
Showing the first eight; more decompositions exist.
