Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459952, here are decompositions:
- 3 + 31459949 = 31459952
- 61 + 31459891 = 31459952
- 103 + 31459849 = 31459952
- 193 + 31459759 = 31459952
- 229 + 31459723 = 31459952
- 331 + 31459621 = 31459952
- 613 + 31459339 = 31459952
- 631 + 31459321 = 31459952
Showing the first eight; more decompositions exist.
