Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143748, here are decompositions:
- 5 + 143743 = 143748
- 19 + 143729 = 143748
- 29 + 143719 = 143748
- 37 + 143711 = 143748
- 61 + 143687 = 143748
- 71 + 143677 = 143748
- 79 + 143669 = 143748
- 97 + 143651 = 143748
Showing the first eight; more decompositions exist.
