Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459708, here are decompositions:
- 11 + 31459697 = 31459708
- 29 + 31459679 = 31459708
- 41 + 31459667 = 31459708
- 47 + 31459661 = 31459708
- 89 + 31459619 = 31459708
- 167 + 31459541 = 31459708
- 191 + 31459517 = 31459708
- 251 + 31459457 = 31459708
Showing the first eight; more decompositions exist.
