Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537922, here are decompositions:
- 19 + 31537903 = 31537922
- 61 + 31537861 = 31537922
- 79 + 31537843 = 31537922
- 181 + 31537741 = 31537922
- 313 + 31537609 = 31537922
- 331 + 31537591 = 31537922
- 349 + 31537573 = 31537922
- 379 + 31537543 = 31537922
Showing the first eight; more decompositions exist.
