Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523580, here are decompositions:
- 41 + 31523539 = 31523580
- 43 + 31523537 = 31523580
- 59 + 31523521 = 31523580
- 103 + 31523477 = 31523580
- 107 + 31523473 = 31523580
- 113 + 31523467 = 31523580
- 139 + 31523441 = 31523580
- 173 + 31523407 = 31523580
Showing the first eight; more decompositions exist.
