Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525872, here are decompositions:
- 3 + 525869 = 525872
- 103 + 525769 = 525872
- 163 + 525709 = 525872
- 223 + 525649 = 525872
- 331 + 525541 = 525872
- 379 + 525493 = 525872
- 433 + 525439 = 525872
- 439 + 525433 = 525872
Showing the first eight; more decompositions exist.
