Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87574, here are decompositions:

17 + 87557 = 87574
83 + 87491 = 87574
101 + 87473 = 87574
131 + 87443 = 87574
167 + 87407 = 87574
191 + 87383 = 87574
251 + 87323 = 87574
257 + 87317 = 87574

Showing the first eight; more decompositions exist.
