Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504948, here are decompositions:

5 + 31504943 = 31504948
149 + 31504799 = 31504948
257 + 31504691 = 31504948
281 + 31504667 = 31504948
401 + 31504547 = 31504948
467 + 31504481 = 31504948
509 + 31504439 = 31504948
719 + 31504229 = 31504948

Showing the first eight; more decompositions exist.
