Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623580, here are decompositions:
- 59 + 31623521 = 31623580
- 71 + 31623509 = 31623580
- 83 + 31623497 = 31623580
- 89 + 31623491 = 31623580
- 101 + 31623479 = 31623580
- 137 + 31623443 = 31623580
- 467 + 31623113 = 31623580
- 557 + 31623023 = 31623580
Showing the first eight; more decompositions exist.
