Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145476, here are decompositions:

5 + 145471 = 145476
13 + 145463 = 145476
17 + 145459 = 145476
43 + 145433 = 145476
53 + 145423 = 145476
59 + 145417 = 145476
127 + 145349 = 145476
173 + 145303 = 145476

Showing the first eight; more decompositions exist.
