Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87438, here are decompositions:

5 + 87433 = 87438
11 + 87427 = 87438
17 + 87421 = 87438
31 + 87407 = 87438
79 + 87359 = 87438
101 + 87337 = 87438
139 + 87299 = 87438
157 + 87281 = 87438

Showing the first eight; more decompositions exist.
