Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459350, here are decompositions:
- 7 + 31459343 = 31459350
- 11 + 31459339 = 31459350
- 29 + 31459321 = 31459350
- 59 + 31459291 = 31459350
- 61 + 31459289 = 31459350
- 89 + 31459261 = 31459350
- 127 + 31459223 = 31459350
- 149 + 31459201 = 31459350
Showing the first eight; more decompositions exist.
