Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15572, here are decompositions:
- 3 + 15569 = 15572
- 13 + 15559 = 15572
- 31 + 15541 = 15572
- 61 + 15511 = 15572
- 79 + 15493 = 15572
- 181 + 15391 = 15572
- 199 + 15373 = 15572
- 211 + 15361 = 15572
Showing the first eight; more decompositions exist.
