Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972542, here are decompositions:
- 61 + 4294972481 = 4294972542
- 101 + 4294972441 = 4294972542
- 109 + 4294972433 = 4294972542
- 131 + 4294972411 = 4294972542
- 149 + 4294972393 = 4294972542
- 191 + 4294972351 = 4294972542
- 251 + 4294972291 = 4294972542
- 433 + 4294972109 = 4294972542
Showing the first eight; more decompositions exist.
