Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462308, here are decompositions:
- 19 + 31462289 = 31462308
- 41 + 31462267 = 31462308
- 167 + 31462141 = 31462308
- 181 + 31462127 = 31462308
- 239 + 31462069 = 31462308
- 331 + 31461977 = 31462308
- 347 + 31461961 = 31462308
- 359 + 31461949 = 31462308
Showing the first eight; more decompositions exist.
