Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87446, here are decompositions:

3 + 87443 = 87446
13 + 87433 = 87446
19 + 87427 = 87446
43 + 87403 = 87446
109 + 87337 = 87446
193 + 87253 = 87446
223 + 87223 = 87446
313 + 87133 = 87446

Showing the first eight; more decompositions exist.
