Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15486, here are decompositions:
- 13 + 15473 = 15486
- 19 + 15467 = 15486
- 43 + 15443 = 15486
- 47 + 15439 = 15486
- 59 + 15427 = 15486
- 73 + 15413 = 15486
- 103 + 15383 = 15486
- 109 + 15377 = 15486
Showing the first eight; more decompositions exist.
