Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 48438, here are decompositions:
- 29 + 48409 = 48438
- 31 + 48407 = 48438
- 41 + 48397 = 48438
- 67 + 48371 = 48438
- 97 + 48341 = 48438
- 101 + 48337 = 48438
- 127 + 48311 = 48438
- 139 + 48299 = 48438
Showing the first eight; more decompositions exist.
