Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80040, here are decompositions:
- 19 + 80021 = 80040
- 41 + 79999 = 80040
- 43 + 79997 = 80040
- 53 + 79987 = 80040
- 61 + 79979 = 80040
- 67 + 79973 = 80040
- 73 + 79967 = 80040
- 97 + 79943 = 80040
Showing the first eight; more decompositions exist.
