Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537550, here are decompositions:
- 3 + 31537547 = 31537550
- 7 + 31537543 = 31537550
- 43 + 31537507 = 31537550
- 73 + 31537477 = 31537550
- 211 + 31537339 = 31537550
- 223 + 31537327 = 31537550
- 241 + 31537309 = 31537550
- 277 + 31537273 = 31537550
Showing the first eight; more decompositions exist.
