Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63980, here are decompositions:
- 3 + 63977 = 63980
- 31 + 63949 = 63980
- 67 + 63913 = 63980
- 73 + 63907 = 63980
- 79 + 63901 = 63980
- 127 + 63853 = 63980
- 139 + 63841 = 63980
- 157 + 63823 = 63980
Showing the first eight; more decompositions exist.
