Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 44390, here are decompositions:
- 7 + 44383 = 44390
- 19 + 44371 = 44390
- 97 + 44293 = 44390
- 109 + 44281 = 44390
- 127 + 44263 = 44390
- 211 + 44179 = 44390
- 271 + 44119 = 44390
- 331 + 44059 = 44390
Showing the first eight; more decompositions exist.
