Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522580, here are decompositions:
- 31 + 31522549 = 31522580
- 139 + 31522441 = 31522580
- 223 + 31522357 = 31522580
- 241 + 31522339 = 31522580
- 283 + 31522297 = 31522580
- 337 + 31522243 = 31522580
- 373 + 31522207 = 31522580
- 601 + 31521979 = 31522580
Showing the first eight; more decompositions exist.
