Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537530, here are decompositions:

7 + 33537523 = 33537530
97 + 33537433 = 33537530
331 + 33537199 = 33537530
409 + 33537121 = 33537530
547 + 33536983 = 33537530
643 + 33536887 = 33537530
823 + 33536707 = 33537530
853 + 33536677 = 33537530

Showing the first eight; more decompositions exist.
