Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125532, here are decompositions:
- 5 + 125527 = 125532
- 23 + 125509 = 125532
- 61 + 125471 = 125532
- 79 + 125453 = 125532
- 103 + 125429 = 125532
- 109 + 125423 = 125532
- 149 + 125383 = 125532
- 179 + 125353 = 125532
Showing the first eight; more decompositions exist.
