Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42972, here are decompositions:
- 5 + 42967 = 42972
- 11 + 42961 = 42972
- 19 + 42953 = 42972
- 29 + 42943 = 42972
- 43 + 42929 = 42972
- 71 + 42901 = 42972
- 73 + 42899 = 42972
- 109 + 42863 = 42972
Showing the first eight; more decompositions exist.
