Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87744, here are decompositions:

5 + 87739 = 87744
23 + 87721 = 87744
43 + 87701 = 87744
47 + 87697 = 87744
53 + 87691 = 87744
61 + 87683 = 87744
73 + 87671 = 87744
101 + 87643 = 87744

Showing the first eight; more decompositions exist.
