Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627072, here are decompositions:
- 3 + 31627069 = 31627072
- 173 + 31626899 = 31627072
- 179 + 31626893 = 31627072
- 233 + 31626839 = 31627072
- 383 + 31626689 = 31627072
- 509 + 31626563 = 31627072
- 683 + 31626389 = 31627072
- 839 + 31626233 = 31627072
Showing the first eight; more decompositions exist.
