Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545574, here are decompositions:

23 + 545551 = 545574
31 + 545543 = 545574
41 + 545533 = 545574
47 + 545527 = 545574
53 + 545521 = 545574
97 + 545477 = 545574
101 + 545473 = 545574
131 + 545443 = 545574

Showing the first eight; more decompositions exist.
