Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479582, here are decompositions:

5 + 31479577 = 31479582
23 + 31479559 = 31479582
31 + 31479551 = 31479582
41 + 31479541 = 31479582
83 + 31479499 = 31479582
163 + 31479419 = 31479582
283 + 31479299 = 31479582
293 + 31479289 = 31479582

Showing the first eight; more decompositions exist.
