Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586436, here are decompositions:
- 29 + 31586407 = 31586436
- 59 + 31586377 = 31586436
- 97 + 31586339 = 31586436
- 149 + 31586287 = 31586436
- 163 + 31586273 = 31586436
- 179 + 31586257 = 31586436
- 199 + 31586237 = 31586436
- 359 + 31586077 = 31586436
Showing the first eight; more decompositions exist.
