Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1478, here are decompositions:
- 7 + 1471 = 1478
- 19 + 1459 = 1478
- 31 + 1447 = 1478
- 79 + 1399 = 1478
- 97 + 1381 = 1478
- 151 + 1327 = 1478
- 157 + 1321 = 1478
- 181 + 1297 = 1478
Showing the first eight; more decompositions exist.
