Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477908, here are decompositions:
- 29 + 31477879 = 31477908
- 31 + 31477877 = 31477908
- 37 + 31477871 = 31477908
- 67 + 31477841 = 31477908
- 97 + 31477811 = 31477908
- 109 + 31477799 = 31477908
- 127 + 31477781 = 31477908
- 149 + 31477759 = 31477908
Showing the first eight; more decompositions exist.
