Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 35720, here are decompositions:

43 + 35677 = 35720
103 + 35617 = 35720
127 + 35593 = 35720
151 + 35569 = 35720
193 + 35527 = 35720
199 + 35521 = 35720
211 + 35509 = 35720
229 + 35491 = 35720

Showing the first eight; more decompositions exist.
