Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90906, here are decompositions:
- 5 + 90901 = 90906
- 19 + 90887 = 90906
- 43 + 90863 = 90906
- 59 + 90847 = 90906
- 73 + 90833 = 90906
- 83 + 90823 = 90906
- 103 + 90803 = 90906
- 113 + 90793 = 90906
Showing the first eight; more decompositions exist.
