Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90804, here are decompositions:
- 11 + 90793 = 90804
- 17 + 90787 = 90804
- 73 + 90731 = 90804
- 101 + 90703 = 90804
- 107 + 90697 = 90804
- 127 + 90677 = 90804
- 157 + 90647 = 90804
- 163 + 90641 = 90804
Showing the first eight; more decompositions exist.
