Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547580, here are decompositions:
- 23 + 31547557 = 31547580
- 41 + 31547539 = 31547580
- 61 + 31547519 = 31547580
- 73 + 31547507 = 31547580
- 101 + 31547479 = 31547580
- 109 + 31547471 = 31547580
- 131 + 31547449 = 31547580
- 139 + 31547441 = 31547580
Showing the first eight; more decompositions exist.
