Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75642, here are decompositions:

13 + 75629 = 75642
23 + 75619 = 75642
31 + 75611 = 75642
59 + 75583 = 75642
71 + 75571 = 75642
89 + 75553 = 75642
101 + 75541 = 75642
103 + 75539 = 75642

Showing the first eight; more decompositions exist.
