Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165416, here are decompositions:
- 19 + 165397 = 165416
- 37 + 165379 = 165416
- 67 + 165349 = 165416
- 73 + 165343 = 165416
- 103 + 165313 = 165416
- 283 + 165133 = 165416
- 313 + 165103 = 165416
- 337 + 165079 = 165416
Showing the first eight; more decompositions exist.
