Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538580, here are decompositions:

37 + 33538543 = 33538580
73 + 33538507 = 33538580
139 + 33538441 = 33538580
193 + 33538387 = 33538580
241 + 33538339 = 33538580
277 + 33538303 = 33538580
307 + 33538273 = 33538580
349 + 33538231 = 33538580

Showing the first eight; more decompositions exist.
