Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497052, here are decompositions:
- 89 + 31496963 = 31497052
- 131 + 31496921 = 31497052
- 179 + 31496873 = 31497052
- 233 + 31496819 = 31497052
- 269 + 31496783 = 31497052
- 311 + 31496741 = 31497052
- 359 + 31496693 = 31497052
- 383 + 31496669 = 31497052
Showing the first eight; more decompositions exist.
