Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20346, here are decompositions:
- 5 + 20341 = 20346
- 13 + 20333 = 20346
- 19 + 20327 = 20346
- 23 + 20323 = 20346
- 59 + 20287 = 20346
- 97 + 20249 = 20346
- 113 + 20233 = 20346
- 127 + 20219 = 20346
Showing the first eight; more decompositions exist.
