Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972, here are decompositions:
- 5 + 967 = 972
- 19 + 953 = 972
- 31 + 941 = 972
- 43 + 929 = 972
- 53 + 919 = 972
- 61 + 911 = 972
- 89 + 883 = 972
- 109 + 863 = 972
Showing the first eight; more decompositions exist.
