Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605326, here are decompositions:
- 7 + 31605319 = 31605326
- 79 + 31605247 = 31605326
- 97 + 31605229 = 31605326
- 157 + 31605169 = 31605326
- 199 + 31605127 = 31605326
- 229 + 31605097 = 31605326
- 307 + 31605019 = 31605326
- 367 + 31604959 = 31605326
Showing the first eight; more decompositions exist.
