Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15544, here are decompositions:
- 3 + 15541 = 15544
- 17 + 15527 = 15544
- 47 + 15497 = 15544
- 71 + 15473 = 15544
- 83 + 15461 = 15544
- 101 + 15443 = 15544
- 131 + 15413 = 15544
- 167 + 15377 = 15544
Showing the first eight; more decompositions exist.
