Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470336, here are decompositions:
- 13 + 31470323 = 31470336
- 43 + 31470293 = 31470336
- 113 + 31470223 = 31470336
- 127 + 31470209 = 31470336
- 137 + 31470199 = 31470336
- 193 + 31470143 = 31470336
- 239 + 31470097 = 31470336
- 263 + 31470073 = 31470336
Showing the first eight; more decompositions exist.
