Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497106, here are decompositions:
- 23 + 31497083 = 31497106
- 149 + 31496957 = 31497106
- 233 + 31496873 = 31497106
- 569 + 31496537 = 31497106
- 587 + 31496519 = 31497106
- 617 + 31496489 = 31497106
- 677 + 31496429 = 31497106
- 887 + 31496219 = 31497106
Showing the first eight; more decompositions exist.
