Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606740, here are decompositions:
- 13 + 31606727 = 31606740
- 29 + 31606711 = 31606740
- 37 + 31606703 = 31606740
- 43 + 31606697 = 31606740
- 59 + 31606681 = 31606740
- 73 + 31606667 = 31606740
- 79 + 31606661 = 31606740
- 83 + 31606657 = 31606740
Showing the first eight; more decompositions exist.
