Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13572, here are decompositions:
- 5 + 13567 = 13572
- 19 + 13553 = 13572
- 59 + 13513 = 13572
- 73 + 13499 = 13572
- 103 + 13469 = 13572
- 109 + 13463 = 13572
- 131 + 13441 = 13572
- 151 + 13421 = 13572
Showing the first eight; more decompositions exist.
