Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143740, here are decompositions:
- 11 + 143729 = 143740
- 29 + 143711 = 143740
- 41 + 143699 = 143740
- 53 + 143687 = 143740
- 71 + 143669 = 143740
- 89 + 143651 = 143740
- 131 + 143609 = 143740
- 167 + 143573 = 143740
Showing the first eight; more decompositions exist.
