Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471358, here are decompositions:
- 151 + 31471207 = 31471358
- 211 + 31471147 = 31471358
- 307 + 31471051 = 31471358
- 367 + 31470991 = 31471358
- 571 + 31470787 = 31471358
- 577 + 31470781 = 31471358
- 739 + 31470619 = 31471358
- 811 + 31470547 = 31471358
Showing the first eight; more decompositions exist.
