Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74688, here are decompositions:

79 + 74609 = 74688
101 + 74587 = 74688
127 + 74561 = 74688
137 + 74551 = 74688
157 + 74531 = 74688
167 + 74521 = 74688
179 + 74509 = 74688
181 + 74507 = 74688

Showing the first eight; more decompositions exist.
