Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25572, here are decompositions:
- 11 + 25561 = 25572
- 31 + 25541 = 25572
- 101 + 25471 = 25572
- 103 + 25469 = 25572
- 109 + 25463 = 25572
- 149 + 25423 = 25572
- 163 + 25409 = 25572
- 181 + 25391 = 25572
Showing the first eight; more decompositions exist.
