Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1448, here are decompositions:
- 19 + 1429 = 1448
- 67 + 1381 = 1448
- 127 + 1321 = 1448
- 151 + 1297 = 1448
- 157 + 1291 = 1448
- 199 + 1249 = 1448
- 211 + 1237 = 1448
- 277 + 1171 = 1448
Showing the first eight; more decompositions exist.
