Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8090, here are decompositions:
- 3 + 8087 = 8090
- 31 + 8059 = 8090
- 37 + 8053 = 8090
- 73 + 8017 = 8090
- 79 + 8011 = 8090
- 97 + 7993 = 8090
- 127 + 7963 = 8090
- 139 + 7951 = 8090
Showing the first eight; more decompositions exist.
