Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541632, here are decompositions:
- 41 + 31541591 = 31541632
- 149 + 31541483 = 31541632
- 233 + 31541399 = 31541632
- 389 + 31541243 = 31541632
- 491 + 31541141 = 31541632
- 503 + 31541129 = 31541632
- 593 + 31541039 = 31541632
- 641 + 31540991 = 31541632
Showing the first eight; more decompositions exist.
