Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537024, here are decompositions:
- 23 + 31537001 = 31537024
- 41 + 31536983 = 31537024
- 107 + 31536917 = 31537024
- 251 + 31536773 = 31537024
- 293 + 31536731 = 31537024
- 317 + 31536707 = 31537024
- 503 + 31536521 = 31537024
- 641 + 31536383 = 31537024
Showing the first eight; more decompositions exist.
