Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504632, here are decompositions:

13 + 31504619 = 31504632
41 + 31504591 = 31504632
59 + 31504573 = 31504632
139 + 31504493 = 31504632
151 + 31504481 = 31504632
179 + 31504453 = 31504632
193 + 31504439 = 31504632
281 + 31504351 = 31504632

Showing the first eight; more decompositions exist.
