Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537134, here are decompositions:
- 7 + 31537127 = 31537134
- 37 + 31537097 = 31537134
- 47 + 31537087 = 31537134
- 107 + 31537027 = 31537134
- 131 + 31537003 = 31537134
- 151 + 31536983 = 31537134
- 191 + 31536943 = 31537134
- 197 + 31536937 = 31537134
Showing the first eight; more decompositions exist.
