Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85072, here are decompositions:
- 11 + 85061 = 85072
- 23 + 85049 = 85072
- 263 + 84809 = 85072
- 311 + 84761 = 85072
- 353 + 84719 = 85072
- 359 + 84713 = 85072
- 419 + 84653 = 85072
- 443 + 84629 = 85072
Showing the first eight; more decompositions exist.
