Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72984, here are decompositions:
- 7 + 72977 = 72984
- 11 + 72973 = 72984
- 31 + 72953 = 72984
- 47 + 72937 = 72984
- 53 + 72931 = 72984
- 61 + 72923 = 72984
- 73 + 72911 = 72984
- 83 + 72901 = 72984
Showing the first eight; more decompositions exist.
