Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507890, here are decompositions:

37 + 33507853 = 33507890
109 + 33507781 = 33507890
127 + 33507763 = 33507890
139 + 33507751 = 33507890
211 + 33507679 = 33507890
313 + 33507577 = 33507890
349 + 33507541 = 33507890
571 + 33507319 = 33507890

Showing the first eight; more decompositions exist.
