Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460880, here are decompositions:
- 7 + 31460873 = 31460880
- 29 + 31460851 = 31460880
- 41 + 31460839 = 31460880
- 43 + 31460837 = 31460880
- 47 + 31460833 = 31460880
- 71 + 31460809 = 31460880
- 89 + 31460791 = 31460880
- 97 + 31460783 = 31460880
Showing the first eight; more decompositions exist.
