Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86040, here are decompositions:
- 11 + 86029 = 86040
- 13 + 86027 = 86040
- 23 + 86017 = 86040
- 29 + 86011 = 86040
- 41 + 85999 = 86040
- 107 + 85933 = 86040
- 109 + 85931 = 86040
- 131 + 85909 = 86040
Showing the first eight; more decompositions exist.
