Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40038, here are decompositions:
- 7 + 40031 = 40038
- 29 + 40009 = 40038
- 59 + 39979 = 40038
- 67 + 39971 = 40038
- 101 + 39937 = 40038
- 109 + 39929 = 40038
- 137 + 39901 = 40038
- 151 + 39887 = 40038
Showing the first eight; more decompositions exist.
