Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459186, here are decompositions:
- 53 + 31459133 = 31459186
- 113 + 31459073 = 31459186
- 167 + 31459019 = 31459186
- 233 + 31458953 = 31459186
- 263 + 31458923 = 31459186
- 389 + 31458797 = 31459186
- 467 + 31458719 = 31459186
- 593 + 31458593 = 31459186
Showing the first eight; more decompositions exist.
