Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538654, here are decompositions:

3 + 538651 = 538654
5 + 538649 = 538654
101 + 538553 = 538654
131 + 538523 = 538654
167 + 538487 = 538654
173 + 538481 = 538654
197 + 538457 = 538654
257 + 538397 = 538654

Showing the first eight; more decompositions exist.
