Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85140, here are decompositions:
- 7 + 85133 = 85140
- 19 + 85121 = 85140
- 31 + 85109 = 85140
- 37 + 85103 = 85140
- 47 + 85093 = 85140
- 53 + 85087 = 85140
- 59 + 85081 = 85140
- 79 + 85061 = 85140
Showing the first eight; more decompositions exist.
