Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521144, here are decompositions:

3 + 33521141 = 33521144
61 + 33521083 = 33521144
157 + 33520987 = 33521144
331 + 33520813 = 33521144
367 + 33520777 = 33521144
457 + 33520687 = 33521144
463 + 33520681 = 33521144
523 + 33520621 = 33521144

Showing the first eight; more decompositions exist.
