Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42312, here are decompositions:
- 5 + 42307 = 42312
- 13 + 42299 = 42312
- 19 + 42293 = 42312
- 29 + 42283 = 42312
- 31 + 42281 = 42312
- 73 + 42239 = 42312
- 89 + 42223 = 42312
- 103 + 42209 = 42312
Showing the first eight; more decompositions exist.
