Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51578, here are decompositions:
- 61 + 51517 = 51578
- 67 + 51511 = 51578
- 97 + 51481 = 51578
- 139 + 51439 = 51578
- 151 + 51427 = 51578
- 157 + 51421 = 51578
- 229 + 51349 = 51578
- 271 + 51307 = 51578
Showing the first eight; more decompositions exist.
