Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15576, here are decompositions:
- 7 + 15569 = 15576
- 17 + 15559 = 15576
- 79 + 15497 = 15576
- 83 + 15493 = 15576
- 103 + 15473 = 15576
- 109 + 15467 = 15576
- 137 + 15439 = 15576
- 149 + 15427 = 15576
Showing the first eight; more decompositions exist.
