Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537026, here are decompositions:
- 23 + 31537003 = 31537026
- 43 + 31536983 = 31537026
- 67 + 31536959 = 31537026
- 83 + 31536943 = 31537026
- 89 + 31536937 = 31537026
- 109 + 31536917 = 31537026
- 163 + 31536863 = 31537026
- 179 + 31536847 = 31537026
Showing the first eight; more decompositions exist.
