Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87510, here are decompositions:
- 19 + 87491 = 87510
- 29 + 87481 = 87510
- 37 + 87473 = 87510
- 67 + 87443 = 87510
- 83 + 87427 = 87510
- 89 + 87421 = 87510
- 103 + 87407 = 87510
- 107 + 87403 = 87510
Showing the first eight; more decompositions exist.
