Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18470, here are decompositions:
- 13 + 18457 = 18470
- 19 + 18451 = 18470
- 31 + 18439 = 18470
- 37 + 18433 = 18470
- 43 + 18427 = 18470
- 73 + 18397 = 18470
- 103 + 18367 = 18470
- 157 + 18313 = 18470
Showing the first eight; more decompositions exist.
