Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40718, here are decompositions:
- 19 + 40699 = 40718
- 79 + 40639 = 40718
- 109 + 40609 = 40718
- 127 + 40591 = 40718
- 199 + 40519 = 40718
- 211 + 40507 = 40718
- 331 + 40387 = 40718
- 367 + 40351 = 40718
Showing the first eight; more decompositions exist.
