Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504484, here are decompositions:

3 + 31504481 = 31504484
31 + 31504453 = 31504484
97 + 31504387 = 31504484
127 + 31504357 = 31504484
157 + 31504327 = 31504484
181 + 31504303 = 31504484
283 + 31504201 = 31504484
397 + 31504087 = 31504484

Showing the first eight; more decompositions exist.
