Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460000, here are decompositions:
- 7 + 31459993 = 31460000
- 37 + 31459963 = 31460000
- 109 + 31459891 = 31460000
- 151 + 31459849 = 31460000
- 193 + 31459807 = 31460000
- 241 + 31459759 = 31460000
- 277 + 31459723 = 31460000
- 283 + 31459717 = 31460000
Showing the first eight; more decompositions exist.
