Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90908, here are decompositions:
- 7 + 90901 = 90908
- 61 + 90847 = 90908
- 67 + 90841 = 90908
- 199 + 90709 = 90908
- 211 + 90697 = 90908
- 229 + 90679 = 90908
- 277 + 90631 = 90908
- 379 + 90529 = 90908
Showing the first eight; more decompositions exist.
