Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45728, here are decompositions:

31 + 45697 = 45728
37 + 45691 = 45728
61 + 45667 = 45728
97 + 45631 = 45728
139 + 45589 = 45728
367 + 45361 = 45728
409 + 45319 = 45728
421 + 45307 = 45728

Showing the first eight; more decompositions exist.
