Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125526, here are decompositions:
- 17 + 125509 = 125526
- 19 + 125507 = 125526
- 29 + 125497 = 125526
- 73 + 125453 = 125526
- 97 + 125429 = 125526
- 103 + 125423 = 125526
- 127 + 125399 = 125526
- 139 + 125387 = 125526
Showing the first eight; more decompositions exist.
