Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72000, here are decompositions:
- 7 + 71993 = 72000
- 13 + 71987 = 72000
- 17 + 71983 = 72000
- 29 + 71971 = 72000
- 37 + 71963 = 72000
- 53 + 71947 = 72000
- 59 + 71941 = 72000
- 67 + 71933 = 72000
Showing the first eight; more decompositions exist.
