Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90642, here are decompositions:
- 11 + 90631 = 90642
- 23 + 90619 = 90642
- 43 + 90599 = 90642
- 59 + 90583 = 90642
- 109 + 90533 = 90642
- 113 + 90529 = 90642
- 131 + 90511 = 90642
- 173 + 90469 = 90642
Showing the first eight; more decompositions exist.
