Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545644, here are decompositions:

3 + 545641 = 545644
23 + 545621 = 545644
101 + 545543 = 545644
167 + 545477 = 545644
257 + 545387 = 545644
353 + 545291 = 545644
431 + 545213 = 545644
503 + 545141 = 545644

Showing the first eight; more decompositions exist.
