Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1250, here are decompositions:
- 13 + 1237 = 1250
- 19 + 1231 = 1250
- 37 + 1213 = 1250
- 79 + 1171 = 1250
- 97 + 1153 = 1250
- 127 + 1123 = 1250
- 157 + 1093 = 1250
- 163 + 1087 = 1250
Showing the first eight; more decompositions exist.
