Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473826, here are decompositions:
- 349 + 2147473477 = 2147473826
- 397 + 2147473429 = 2147473826
- 457 + 2147473369 = 2147473826
- 709 + 2147473117 = 2147473826
- 1039 + 2147472787 = 2147473826
- 1069 + 2147472757 = 2147473826
- 1129 + 2147472697 = 2147473826
- 1327 + 2147472499 = 2147473826
Showing the first eight; more decompositions exist.
