Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87542, here are decompositions:

3 + 87539 = 87542
19 + 87523 = 87542
31 + 87511 = 87542
61 + 87481 = 87542
109 + 87433 = 87542
139 + 87403 = 87542
229 + 87313 = 87542
331 + 87211 = 87542

Showing the first eight; more decompositions exist.
