Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972672, here are decompositions:
- 59 + 4294972613 = 4294972672
- 113 + 4294972559 = 4294972672
- 191 + 4294972481 = 4294972672
- 239 + 4294972433 = 4294972672
- 251 + 4294972421 = 4294972672
- 521 + 4294972151 = 4294972672
- 563 + 4294972109 = 4294972672
- 593 + 4294972079 = 4294972672
Showing the first eight; more decompositions exist.
