Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145892, here are decompositions:
- 13 + 145879 = 145892
- 31 + 145861 = 145892
- 73 + 145819 = 145892
- 139 + 145753 = 145892
- 211 + 145681 = 145892
- 349 + 145543 = 145892
- 379 + 145513 = 145892
- 421 + 145471 = 145892
Showing the first eight; more decompositions exist.
