Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504498, here are decompositions:

5 + 31504493 = 31504498
17 + 31504481 = 31504498
59 + 31504439 = 31504498
131 + 31504367 = 31504498
269 + 31504229 = 31504498
401 + 31504097 = 31504498
461 + 31504037 = 31504498
521 + 31503977 = 31504498

Showing the first eight; more decompositions exist.
