Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487956, here are decompositions:
- 13 + 487943 = 487956
- 23 + 487933 = 487956
- 59 + 487897 = 487956
- 67 + 487889 = 487956
- 83 + 487873 = 487956
- 113 + 487843 = 487956
- 127 + 487829 = 487956
- 137 + 487819 = 487956
Showing the first eight; more decompositions exist.
