Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15470, here are decompositions:
- 3 + 15467 = 15470
- 19 + 15451 = 15470
- 31 + 15439 = 15470
- 43 + 15427 = 15470
- 79 + 15391 = 15470
- 97 + 15373 = 15470
- 109 + 15361 = 15470
- 139 + 15331 = 15470
Showing the first eight; more decompositions exist.
