Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90540, here are decompositions:
- 7 + 90533 = 90540
- 11 + 90529 = 90540
- 13 + 90527 = 90540
- 17 + 90523 = 90540
- 29 + 90511 = 90540
- 41 + 90499 = 90540
- 59 + 90481 = 90540
- 67 + 90473 = 90540
Showing the first eight; more decompositions exist.
