Goldbach decomposition

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.
