Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90520, here are decompositions:
- 47 + 90473 = 90520
- 83 + 90437 = 90520
- 113 + 90407 = 90520
- 149 + 90371 = 90520
- 167 + 90353 = 90520
- 239 + 90281 = 90520
- 257 + 90263 = 90520
- 281 + 90239 = 90520
Showing the first eight; more decompositions exist.
