Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146544, here are decompositions:

5 + 146539 = 146544
17 + 146527 = 146544
23 + 146521 = 146544
31 + 146513 = 146544
67 + 146477 = 146544
107 + 146437 = 146544
127 + 146417 = 146544
137 + 146407 = 146544

Showing the first eight; more decompositions exist.
