Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43992, here are decompositions:
- 5 + 43987 = 43992
- 19 + 43973 = 43992
- 23 + 43969 = 43992
- 29 + 43963 = 43992
- 31 + 43961 = 43992
- 41 + 43951 = 43992
- 59 + 43933 = 43992
- 79 + 43913 = 43992
Showing the first eight; more decompositions exist.
