Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544316, here are decompositions:
- 5 + 31544311 = 31544316
- 19 + 31544297 = 31544316
- 103 + 31544213 = 31544316
- 109 + 31544207 = 31544316
- 127 + 31544189 = 31544316
- 137 + 31544179 = 31544316
- 149 + 31544167 = 31544316
- 163 + 31544153 = 31544316
Showing the first eight; more decompositions exist.
