Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537878, here are decompositions:

109 + 33537769 = 33537878
307 + 33537571 = 33537878
337 + 33537541 = 33537878
349 + 33537529 = 33537878
691 + 33537187 = 33537878
757 + 33537121 = 33537878
937 + 33536941 = 33537878
991 + 33536887 = 33537878

Showing the first eight; more decompositions exist.
