Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294973438, here are decompositions:
- 31 + 4294973407 = 4294973438
- 157 + 4294973281 = 4294973438
- 337 + 4294973101 = 4294973438
- 367 + 4294973071 = 4294973438
- 421 + 4294973017 = 4294973438
- 487 + 4294972951 = 4294973438
- 541 + 4294972897 = 4294973438
- 571 + 4294972867 = 4294973438
Showing the first eight; more decompositions exist.
