Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51480, here are decompositions:
- 7 + 51473 = 51480
- 19 + 51461 = 51480
- 31 + 51449 = 51480
- 41 + 51439 = 51480
- 43 + 51437 = 51480
- 53 + 51427 = 51480
- 59 + 51421 = 51480
- 61 + 51419 = 51480
Showing the first eight; more decompositions exist.
