Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87554, here are decompositions:

7 + 87547 = 87554
13 + 87541 = 87554
31 + 87523 = 87554
37 + 87517 = 87554
43 + 87511 = 87554
73 + 87481 = 87554
127 + 87427 = 87554
151 + 87403 = 87554

Showing the first eight; more decompositions exist.
