Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83520, here are decompositions:
- 23 + 83497 = 83520
- 43 + 83477 = 83520
- 61 + 83459 = 83520
- 71 + 83449 = 83520
- 83 + 83437 = 83520
- 89 + 83431 = 83520
- 97 + 83423 = 83520
- 103 + 83417 = 83520
Showing the first eight; more decompositions exist.
