Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15604, here are decompositions:
- 3 + 15601 = 15604
- 23 + 15581 = 15604
- 53 + 15551 = 15604
- 107 + 15497 = 15604
- 131 + 15473 = 15604
- 137 + 15467 = 15604
- 191 + 15413 = 15604
- 227 + 15377 = 15604
Showing the first eight; more decompositions exist.
