Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528846, here are decompositions:
- 3 + 31528843 = 31528846
- 5 + 31528841 = 31528846
- 23 + 31528823 = 31528846
- 149 + 31528697 = 31528846
- 233 + 31528613 = 31528846
- 347 + 31528499 = 31528846
- 509 + 31528337 = 31528846
- 563 + 31528283 = 31528846
Showing the first eight; more decompositions exist.
