Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 41990, here are decompositions:
- 7 + 41983 = 41990
- 31 + 41959 = 41990
- 37 + 41953 = 41990
- 43 + 41947 = 41990
- 79 + 41911 = 41990
- 97 + 41893 = 41990
- 103 + 41887 = 41990
- 127 + 41863 = 41990
Showing the first eight; more decompositions exist.
