Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74390, here are decompositions:
- 7 + 74383 = 74390
- 13 + 74377 = 74390
- 37 + 74353 = 74390
- 67 + 74323 = 74390
- 73 + 74317 = 74390
- 79 + 74311 = 74390
- 97 + 74293 = 74390
- 103 + 74287 = 74390
Showing the first eight; more decompositions exist.
