Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504548, here are decompositions:

67 + 31504481 = 31504548
109 + 31504439 = 31504548
181 + 31504367 = 31504548
191 + 31504357 = 31504548
197 + 31504351 = 31504548
347 + 31504201 = 31504548
359 + 31504189 = 31504548
419 + 31504129 = 31504548

Showing the first eight; more decompositions exist.
