Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64140, here are decompositions:
- 17 + 64123 = 64140
- 31 + 64109 = 64140
- 59 + 64081 = 64140
- 73 + 64067 = 64140
- 103 + 64037 = 64140
- 107 + 64033 = 64140
- 127 + 64013 = 64140
- 163 + 63977 = 64140
Showing the first eight; more decompositions exist.
