Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1418, here are decompositions:
- 19 + 1399 = 1418
- 37 + 1381 = 1418
- 97 + 1321 = 1418
- 127 + 1291 = 1418
- 139 + 1279 = 1418
- 181 + 1237 = 1418
- 331 + 1087 = 1418
- 349 + 1069 = 1418
Showing the first eight; more decompositions exist.
