Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13190, here are decompositions:
- 3 + 13187 = 13190
- 7 + 13183 = 13190
- 13 + 13177 = 13190
- 19 + 13171 = 13190
- 31 + 13159 = 13190
- 43 + 13147 = 13190
- 97 + 13093 = 13190
- 127 + 13063 = 13190
Showing the first eight; more decompositions exist.
