Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537264, here are decompositions:
- 41 + 31537223 = 31537264
- 113 + 31537151 = 31537264
- 131 + 31537133 = 31537264
- 137 + 31537127 = 31537264
- 167 + 31537097 = 31537264
- 263 + 31537001 = 31537264
- 281 + 31536983 = 31537264
- 347 + 31536917 = 31537264
Showing the first eight; more decompositions exist.
