Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15562, here are decompositions:
- 3 + 15559 = 15562
- 11 + 15551 = 15562
- 89 + 15473 = 15562
- 101 + 15461 = 15562
- 149 + 15413 = 15562
- 179 + 15383 = 15562
- 233 + 15329 = 15562
- 263 + 15299 = 15562
Showing the first eight; more decompositions exist.
