Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79980, here are decompositions:
- 7 + 79973 = 79980
- 13 + 79967 = 79980
- 37 + 79943 = 79980
- 41 + 79939 = 79980
- 73 + 79907 = 79980
- 79 + 79901 = 79980
- 107 + 79873 = 79980
- 113 + 79867 = 79980
Showing the first eight; more decompositions exist.
