Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19088, here are decompositions:
- 7 + 19081 = 19088
- 19 + 19069 = 19088
- 37 + 19051 = 19088
- 79 + 19009 = 19088
- 109 + 18979 = 19088
- 229 + 18859 = 19088
- 331 + 18757 = 19088
- 397 + 18691 = 19088
Showing the first eight; more decompositions exist.
