Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23478, here are decompositions:
- 5 + 23473 = 23478
- 19 + 23459 = 23478
- 31 + 23447 = 23478
- 47 + 23431 = 23478
- 61 + 23417 = 23478
- 79 + 23399 = 23478
- 107 + 23371 = 23478
- 109 + 23369 = 23478
Showing the first eight; more decompositions exist.
