Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33623642, here are decompositions:

43 + 33623599 = 33623642
79 + 33623563 = 33623642
139 + 33623503 = 33623642
223 + 33623419 = 33623642
271 + 33623371 = 33623642
313 + 33623329 = 33623642
541 + 33623101 = 33623642
571 + 33623071 = 33623642

Showing the first eight; more decompositions exist.
