Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294973972, here are decompositions:
- 19 + 4294973953 = 4294973972
- 61 + 4294973911 = 4294973972
- 73 + 4294973899 = 4294973972
- 103 + 4294973869 = 4294973972
- 181 + 4294973791 = 4294973972
- 229 + 4294973743 = 4294973972
- 379 + 4294973593 = 4294973972
- 433 + 4294973539 = 4294973972
Showing the first eight; more decompositions exist.
