Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605470, here are decompositions:
- 31 + 31605439 = 31605470
- 109 + 31605361 = 31605470
- 151 + 31605319 = 31605470
- 199 + 31605271 = 31605470
- 223 + 31605247 = 31605470
- 241 + 31605229 = 31605470
- 331 + 31605139 = 31605470
- 373 + 31605097 = 31605470
Showing the first eight; more decompositions exist.
