Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504524, here are decompositions:

31 + 31504493 = 31504524
43 + 31504481 = 31504524
71 + 31504453 = 31504524
137 + 31504387 = 31504524
151 + 31504373 = 31504524
157 + 31504367 = 31504524
167 + 31504357 = 31504524
173 + 31504351 = 31504524

Showing the first eight; more decompositions exist.
