Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540576, here are decompositions:
- 3 + 31540573 = 31540576
- 47 + 31540529 = 31540576
- 83 + 31540493 = 31540576
- 233 + 31540343 = 31540576
- 359 + 31540217 = 31540576
- 467 + 31540109 = 31540576
- 563 + 31540013 = 31540576
- 569 + 31540007 = 31540576
Showing the first eight; more decompositions exist.
