Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512972, here are decompositions:

13 + 33512959 = 33512972
43 + 33512929 = 33512972
193 + 33512779 = 33512972
331 + 33512641 = 33512972
439 + 33512533 = 33512972
541 + 33512431 = 33512972
673 + 33512299 = 33512972
709 + 33512263 = 33512972

Showing the first eight; more decompositions exist.
