Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 35780, here are decompositions:

103 + 35677 = 35780
109 + 35671 = 35780
163 + 35617 = 35780
211 + 35569 = 35780
271 + 35509 = 35780
331 + 35449 = 35780
373 + 35407 = 35780
379 + 35401 = 35780

Showing the first eight; more decompositions exist.
