Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8190, here are decompositions:
- 11 + 8179 = 8190
- 19 + 8171 = 8190
- 23 + 8167 = 8190
- 29 + 8161 = 8190
- 43 + 8147 = 8190
- 67 + 8123 = 8190
- 73 + 8117 = 8190
- 79 + 8111 = 8190
Showing the first eight; more decompositions exist.
