Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459032, here are decompositions:
- 13 + 31459019 = 31459032
- 79 + 31458953 = 31459032
- 109 + 31458923 = 31459032
- 131 + 31458901 = 31459032
- 211 + 31458821 = 31459032
- 233 + 31458799 = 31459032
- 271 + 31458761 = 31459032
- 313 + 31458719 = 31459032
Showing the first eight; more decompositions exist.
