Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40590, here are decompositions:
- 7 + 40583 = 40590
- 13 + 40577 = 40590
- 31 + 40559 = 40590
- 47 + 40543 = 40590
- 59 + 40531 = 40590
- 61 + 40529 = 40590
- 71 + 40519 = 40590
- 83 + 40507 = 40590
Showing the first eight; more decompositions exist.
