Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40998, here are decompositions:
- 5 + 40993 = 40998
- 37 + 40961 = 40998
- 59 + 40939 = 40998
- 71 + 40927 = 40998
- 101 + 40897 = 40998
- 131 + 40867 = 40998
- 149 + 40849 = 40998
- 151 + 40847 = 40998
Showing the first eight; more decompositions exist.
