Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595616, here are decompositions:
- 5 + 31595611 = 31595616
- 23 + 31595593 = 31595616
- 43 + 31595573 = 31595616
- 47 + 31595569 = 31595616
- 149 + 31595467 = 31595616
- 223 + 31595393 = 31595616
- 229 + 31595387 = 31595616
- 233 + 31595383 = 31595616
Showing the first eight; more decompositions exist.
