Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497094, here are decompositions:
- 11 + 31497083 = 31497094
- 23 + 31497071 = 31497094
- 131 + 31496963 = 31497094
- 137 + 31496957 = 31497094
- 173 + 31496921 = 31497094
- 311 + 31496783 = 31497094
- 353 + 31496741 = 31497094
- 401 + 31496693 = 31497094
Showing the first eight; more decompositions exist.
