Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496030, here are decompositions:

3 + 31496027 = 31496030
19 + 31496011 = 31496030
109 + 31495921 = 31496030
151 + 31495879 = 31496030
211 + 31495819 = 31496030
229 + 31495801 = 31496030
277 + 31495753 = 31496030
337 + 31495693 = 31496030

Showing the first eight; more decompositions exist.
