Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31621244, here are decompositions:
- 7 + 31621237 = 31621244
- 103 + 31621141 = 31621244
- 163 + 31621081 = 31621244
- 181 + 31621063 = 31621244
- 211 + 31621033 = 31621244
- 271 + 31620973 = 31621244
- 307 + 31620937 = 31621244
- 313 + 31620931 = 31621244
Showing the first eight; more decompositions exist.
