Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478592, here are decompositions:

11 + 31478581 = 31478592
71 + 31478521 = 31478592
109 + 31478483 = 31478592
113 + 31478479 = 31478592
163 + 31478429 = 31478592
181 + 31478411 = 31478592
191 + 31478401 = 31478592
193 + 31478399 = 31478592

Showing the first eight; more decompositions exist.
