Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497646, here are decompositions:
- 179 + 31497467 = 31497646
- 197 + 31497449 = 31497646
- 293 + 31497353 = 31497646
- 347 + 31497299 = 31497646
- 353 + 31497293 = 31497646
- 359 + 31497287 = 31497646
- 563 + 31497083 = 31497646
- 683 + 31496963 = 31497646
Showing the first eight; more decompositions exist.
