Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980, here are decompositions:
- 3 + 977 = 980
- 13 + 967 = 980
- 43 + 937 = 980
- 61 + 919 = 980
- 73 + 907 = 980
- 97 + 883 = 980
- 103 + 877 = 980
- 127 + 853 = 980
Showing the first eight; more decompositions exist.
