Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537150, here are decompositions:
- 3 + 31537147 = 31537150
- 17 + 31537133 = 31537150
- 23 + 31537127 = 31537150
- 53 + 31537097 = 31537150
- 101 + 31537049 = 31537150
- 107 + 31537043 = 31537150
- 149 + 31537001 = 31537150
- 167 + 31536983 = 31537150
Showing the first eight; more decompositions exist.
