Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90538, here are decompositions:
- 5 + 90533 = 90538
- 11 + 90527 = 90538
- 101 + 90437 = 90538
- 131 + 90407 = 90538
- 137 + 90401 = 90538
- 167 + 90371 = 90538
- 179 + 90359 = 90538
- 257 + 90281 = 90538
Showing the first eight; more decompositions exist.
