Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506604, here are decompositions:

5 + 31506599 = 31506604
83 + 31506521 = 31506604
167 + 31506437 = 31506604
251 + 31506353 = 31506604
293 + 31506311 = 31506604
431 + 31506173 = 31506604
677 + 31505927 = 31506604
683 + 31505921 = 31506604

Showing the first eight; more decompositions exist.
