Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19382, here are decompositions:
- 3 + 19379 = 19382
- 73 + 19309 = 19382
- 109 + 19273 = 19382
- 151 + 19231 = 19382
- 163 + 19219 = 19382
- 199 + 19183 = 19382
- 241 + 19141 = 19382
- 313 + 19069 = 19382
Showing the first eight; more decompositions exist.
