Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81600, here are decompositions:
- 31 + 81569 = 81600
- 37 + 81563 = 81600
- 41 + 81559 = 81600
- 47 + 81553 = 81600
- 53 + 81547 = 81600
- 67 + 81533 = 81600
- 73 + 81527 = 81600
- 83 + 81517 = 81600
Showing the first eight; more decompositions exist.
