Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504268, here are decompositions:

67 + 31504201 = 31504268
79 + 31504189 = 31504268
139 + 31504129 = 31504268
181 + 31504087 = 31504268
307 + 31503961 = 31504268
337 + 31503931 = 31504268
421 + 31503847 = 31504268
457 + 31503811 = 31504268

Showing the first eight; more decompositions exist.
