Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479622, here are decompositions:

3 + 31479619 = 31479622
29 + 31479593 = 31479622
71 + 31479551 = 31479622
131 + 31479491 = 31479622
353 + 31479269 = 31479622
491 + 31479131 = 31479622
521 + 31479101 = 31479622
653 + 31478969 = 31479622

Showing the first eight; more decompositions exist.
