Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540022, here are decompositions:
- 13 + 31540009 = 31540022
- 373 + 31539649 = 31540022
- 379 + 31539643 = 31540022
- 439 + 31539583 = 31540022
- 499 + 31539523 = 31540022
- 523 + 31539499 = 31540022
- 601 + 31539421 = 31540022
- 673 + 31539349 = 31540022
Showing the first eight; more decompositions exist.
