Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53438, here are decompositions:
- 19 + 53419 = 53438
- 31 + 53407 = 53438
- 37 + 53401 = 53438
- 61 + 53377 = 53438
- 79 + 53359 = 53438
- 139 + 53299 = 53438
- 157 + 53281 = 53438
- 199 + 53239 = 53438
Showing the first eight; more decompositions exist.
