Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55438, here are decompositions:
- 101 + 55337 = 55438
- 107 + 55331 = 55438
- 179 + 55259 = 55438
- 311 + 55127 = 55438
- 359 + 55079 = 55438
- 389 + 55049 = 55438
- 479 + 54959 = 55438
- 521 + 54917 = 55438
Showing the first eight; more decompositions exist.
