Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143750, here are decompositions:
- 7 + 143743 = 143750
- 31 + 143719 = 143750
- 73 + 143677 = 143750
- 97 + 143653 = 143750
- 157 + 143593 = 143750
- 181 + 143569 = 143750
- 199 + 143551 = 143750
- 223 + 143527 = 143750
Showing the first eight; more decompositions exist.
