Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85240, here are decompositions:
- 3 + 85237 = 85240
- 11 + 85229 = 85240
- 17 + 85223 = 85240
- 41 + 85199 = 85240
- 47 + 85193 = 85240
- 107 + 85133 = 85240
- 131 + 85109 = 85240
- 137 + 85103 = 85240
Showing the first eight; more decompositions exist.
