Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43980, here are decompositions:
- 7 + 43973 = 43980
- 11 + 43969 = 43980
- 17 + 43963 = 43980
- 19 + 43961 = 43980
- 29 + 43951 = 43980
- 37 + 43943 = 43980
- 47 + 43933 = 43980
- 67 + 43913 = 43980
Showing the first eight; more decompositions exist.
