Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75646, here are decompositions:

5 + 75641 = 75646
17 + 75629 = 75646
29 + 75617 = 75646
89 + 75557 = 75646
107 + 75539 = 75646
113 + 75533 = 75646
167 + 75479 = 75646
239 + 75407 = 75646

Showing the first eight; more decompositions exist.
