Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140672, here are decompositions:
- 13 + 140659 = 140672
- 43 + 140629 = 140672
- 61 + 140611 = 140672
- 79 + 140593 = 140672
- 139 + 140533 = 140672
- 151 + 140521 = 140672
- 199 + 140473 = 140672
- 223 + 140449 = 140672
Showing the first eight; more decompositions exist.
