Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90442, here are decompositions:
- 3 + 90439 = 90442
- 5 + 90437 = 90442
- 41 + 90401 = 90442
- 71 + 90371 = 90442
- 83 + 90359 = 90442
- 89 + 90353 = 90442
- 179 + 90263 = 90442
- 239 + 90203 = 90442
Showing the first eight; more decompositions exist.
