Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90000, here are decompositions:
- 11 + 89989 = 90000
- 17 + 89983 = 90000
- 23 + 89977 = 90000
- 37 + 89963 = 90000
- 41 + 89959 = 90000
- 61 + 89939 = 90000
- 83 + 89917 = 90000
- 101 + 89899 = 90000
Showing the first eight; more decompositions exist.
