Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 41780, here are decompositions:

3 + 41777 = 41780
19 + 41761 = 41780
43 + 41737 = 41780
61 + 41719 = 41780
139 + 41641 = 41780
163 + 41617 = 41780
241 + 41539 = 41780
313 + 41467 = 41780

Showing the first eight; more decompositions exist.
