Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971938, here are decompositions:
- 7 + 4294971931 = 4294971938
- 79 + 4294971859 = 4294971938
- 97 + 4294971841 = 4294971938
- 109 + 4294971829 = 4294971938
- 157 + 4294971781 = 4294971938
- 331 + 4294971607 = 4294971938
- 547 + 4294971391 = 4294971938
- 571 + 4294971367 = 4294971938
Showing the first eight; more decompositions exist.
