Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471670, here are decompositions:
- 3 + 31471667 = 31471670
- 7 + 31471663 = 31471670
- 31 + 31471639 = 31471670
- 37 + 31471633 = 31471670
- 79 + 31471591 = 31471670
- 283 + 31471387 = 31471670
- 313 + 31471357 = 31471670
- 457 + 31471213 = 31471670
Showing the first eight; more decompositions exist.
