Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72766, here are decompositions:
- 3 + 72763 = 72766
- 47 + 72719 = 72766
- 59 + 72707 = 72766
- 149 + 72617 = 72766
- 233 + 72533 = 72766
- 263 + 72503 = 72766
- 269 + 72497 = 72766
- 383 + 72383 = 72766
Showing the first eight; more decompositions exist.
