Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500484, here are decompositions:

101 + 31500383 = 31500484
107 + 31500377 = 31500484
131 + 31500353 = 31500484
263 + 31500221 = 31500484
383 + 31500101 = 31500484
401 + 31500083 = 31500484
461 + 31500023 = 31500484
467 + 31500017 = 31500484

Showing the first eight; more decompositions exist.
