Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19244, here are decompositions:
- 7 + 19237 = 19244
- 13 + 19231 = 19244
- 31 + 19213 = 19244
- 37 + 19207 = 19244
- 61 + 19183 = 19244
- 103 + 19141 = 19244
- 157 + 19087 = 19244
- 163 + 19081 = 19244
Showing the first eight; more decompositions exist.
