Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99990, here are decompositions:
- 19 + 99971 = 99990
- 29 + 99961 = 99990
- 61 + 99929 = 99990
- 67 + 99923 = 99990
- 83 + 99907 = 99990
- 89 + 99901 = 99990
- 109 + 99881 = 99990
- 113 + 99877 = 99990
Showing the first eight; more decompositions exist.
