Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611636, here are decompositions:
- 19 + 31611617 = 31611636
- 29 + 31611607 = 31611636
- 53 + 31611583 = 31611636
- 59 + 31611577 = 31611636
- 83 + 31611553 = 31611636
- 97 + 31611539 = 31611636
- 109 + 31611527 = 31611636
- 127 + 31611509 = 31611636
Showing the first eight; more decompositions exist.
