Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87700, here are decompositions:

3 + 87697 = 87700
17 + 87683 = 87700
29 + 87671 = 87700
59 + 87641 = 87700
71 + 87629 = 87700
113 + 87587 = 87700
191 + 87509 = 87700
227 + 87473 = 87700

Showing the first eight; more decompositions exist.
