Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140712, here are decompositions:
- 23 + 140689 = 140712
- 29 + 140683 = 140712
- 31 + 140681 = 140712
- 53 + 140659 = 140712
- 73 + 140639 = 140712
- 83 + 140629 = 140712
- 101 + 140611 = 140712
- 109 + 140603 = 140712
Showing the first eight; more decompositions exist.
