Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497436, here are decompositions:
- 83 + 31497353 = 31497436
- 137 + 31497299 = 31497436
- 149 + 31497287 = 31497436
- 353 + 31497083 = 31497436
- 479 + 31496957 = 31497436
- 563 + 31496873 = 31497436
- 617 + 31496819 = 31497436
- 653 + 31496783 = 31497436
Showing the first eight; more decompositions exist.
