Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47690, here are decompositions:
- 31 + 47659 = 47690
- 37 + 47653 = 47690
- 61 + 47629 = 47690
- 67 + 47623 = 47690
- 109 + 47581 = 47690
- 127 + 47563 = 47690
- 157 + 47533 = 47690
- 163 + 47527 = 47690
Showing the first eight; more decompositions exist.
