Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462570, here are decompositions:
- 17 + 31462553 = 31462570
- 23 + 31462547 = 31462570
- 89 + 31462481 = 31462570
- 131 + 31462439 = 31462570
- 137 + 31462433 = 31462570
- 197 + 31462373 = 31462570
- 257 + 31462313 = 31462570
- 281 + 31462289 = 31462570
Showing the first eight; more decompositions exist.
