Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90820, here are decompositions:
- 17 + 90803 = 90820
- 71 + 90749 = 90820
- 89 + 90731 = 90820
- 173 + 90647 = 90820
- 179 + 90641 = 90820
- 293 + 90527 = 90820
- 347 + 90473 = 90820
- 383 + 90437 = 90820
Showing the first eight; more decompositions exist.
