Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85040, here are decompositions:
- 3 + 85037 = 85040
- 13 + 85027 = 85040
- 19 + 85021 = 85040
- 31 + 85009 = 85040
- 61 + 84979 = 85040
- 73 + 84967 = 85040
- 79 + 84961 = 85040
- 127 + 84913 = 85040
Showing the first eight; more decompositions exist.
