Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143972, here are decompositions:
- 19 + 143953 = 143972
- 139 + 143833 = 143972
- 151 + 143821 = 143972
- 181 + 143791 = 143972
- 193 + 143779 = 143972
- 229 + 143743 = 143972
- 379 + 143593 = 143972
- 421 + 143551 = 143972
Showing the first eight; more decompositions exist.
