Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1274, here are decompositions:
- 37 + 1237 = 1274
- 43 + 1231 = 1274
- 61 + 1213 = 1274
- 73 + 1201 = 1274
- 103 + 1171 = 1274
- 151 + 1123 = 1274
- 157 + 1117 = 1274
- 181 + 1093 = 1274
Showing the first eight; more decompositions exist.
