Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497250, here are decompositions:
- 167 + 31497083 = 31497250
- 179 + 31497071 = 31497250
- 293 + 31496957 = 31497250
- 431 + 31496819 = 31497250
- 467 + 31496783 = 31497250
- 509 + 31496741 = 31497250
- 557 + 31496693 = 31497250
- 677 + 31496573 = 31497250
Showing the first eight; more decompositions exist.
