Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537210, here are decompositions:
- 59 + 31537151 = 31537210
- 83 + 31537127 = 31537210
- 113 + 31537097 = 31537210
- 167 + 31537043 = 31537210
- 227 + 31536983 = 31537210
- 251 + 31536959 = 31537210
- 293 + 31536917 = 31537210
- 347 + 31536863 = 31537210
Showing the first eight; more decompositions exist.
