Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87066, here are decompositions:
- 17 + 87049 = 87066
- 29 + 87037 = 87066
- 53 + 87013 = 87066
- 73 + 86993 = 87066
- 97 + 86969 = 87066
- 107 + 86959 = 87066
- 127 + 86939 = 87066
- 137 + 86929 = 87066
Showing the first eight; more decompositions exist.
