Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19250, here are decompositions:
- 13 + 19237 = 19250
- 19 + 19231 = 19250
- 31 + 19219 = 19250
- 37 + 19213 = 19250
- 43 + 19207 = 19250
- 67 + 19183 = 19250
- 109 + 19141 = 19250
- 163 + 19087 = 19250
Showing the first eight; more decompositions exist.
