Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45428, here are decompositions:

67 + 45361 = 45428
109 + 45319 = 45428
139 + 45289 = 45428
181 + 45247 = 45428
307 + 45121 = 45428
367 + 45061 = 45428
421 + 45007 = 45428
457 + 44971 = 45428

Showing the first eight; more decompositions exist.
