Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90478, here are decompositions:
- 5 + 90473 = 90478
- 41 + 90437 = 90478
- 71 + 90407 = 90478
- 107 + 90371 = 90478
- 197 + 90281 = 90478
- 239 + 90239 = 90478
- 251 + 90227 = 90478
- 281 + 90197 = 90478
Showing the first eight; more decompositions exist.
