Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 44040, here are decompositions:
- 11 + 44029 = 44040
- 13 + 44027 = 44040
- 19 + 44021 = 44040
- 23 + 44017 = 44040
- 43 + 43997 = 44040
- 53 + 43987 = 44040
- 67 + 43973 = 44040
- 71 + 43969 = 44040
Showing the first eight; more decompositions exist.
