Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142312, here are decompositions:
- 41 + 142271 = 142312
- 89 + 142223 = 142312
- 101 + 142211 = 142312
- 251 + 142061 = 142312
- 263 + 142049 = 142312
- 281 + 142031 = 142312
- 293 + 142019 = 142312
- 353 + 141959 = 142312
Showing the first eight; more decompositions exist.
