Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459642, here are decompositions:
- 23 + 31459619 = 31459642
- 89 + 31459553 = 31459642
- 101 + 31459541 = 31459642
- 233 + 31459409 = 31459642
- 293 + 31459349 = 31459642
- 353 + 31459289 = 31459642
- 419 + 31459223 = 31459642
- 443 + 31459199 = 31459642
Showing the first eight; more decompositions exist.
