Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497208, here are decompositions:
- 137 + 31497071 = 31497208
- 251 + 31496957 = 31497208
- 389 + 31496819 = 31497208
- 467 + 31496741 = 31497208
- 641 + 31496567 = 31497208
- 719 + 31496489 = 31497208
- 839 + 31496369 = 31497208
- 887 + 31496321 = 31497208
Showing the first eight; more decompositions exist.
