Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1370, here are decompositions:
- 3 + 1367 = 1370
- 43 + 1327 = 1370
- 67 + 1303 = 1370
- 73 + 1297 = 1370
- 79 + 1291 = 1370
- 139 + 1231 = 1370
- 157 + 1213 = 1370
- 199 + 1171 = 1370
Showing the first eight; more decompositions exist.
