Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73728, here are decompositions:

7 + 73721 = 73728
19 + 73709 = 73728
29 + 73699 = 73728
47 + 73681 = 73728
131 + 73597 = 73728
139 + 73589 = 73728
157 + 73571 = 73728
167 + 73561 = 73728

Showing the first eight; more decompositions exist.
