Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565342, here are decompositions:
- 19 + 31565323 = 31565342
- 43 + 31565299 = 31565342
- 223 + 31565119 = 31565342
- 241 + 31565101 = 31565342
- 313 + 31565029 = 31565342
- 409 + 31564933 = 31565342
- 421 + 31564921 = 31565342
- 463 + 31564879 = 31565342
Showing the first eight; more decompositions exist.
