Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125544, here are decompositions:
- 5 + 125539 = 125544
- 17 + 125527 = 125544
- 37 + 125507 = 125544
- 47 + 125497 = 125544
- 73 + 125471 = 125544
- 103 + 125441 = 125544
- 137 + 125407 = 125544
- 157 + 125387 = 125544
Showing the first eight; more decompositions exist.
