Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40044, here are decompositions:
- 5 + 40039 = 40044
- 7 + 40037 = 40044
- 13 + 40031 = 40044
- 31 + 40013 = 40044
- 61 + 39983 = 40044
- 73 + 39971 = 40044
- 107 + 39937 = 40044
- 157 + 39887 = 40044
Showing the first eight; more decompositions exist.
