Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479292, here are decompositions:

3 + 31479289 = 31479292
23 + 31479269 = 31479292
41 + 31479251 = 31479292
191 + 31479101 = 31479292
359 + 31478933 = 31479292
461 + 31478831 = 31479292
653 + 31478639 = 31479292
809 + 31478483 = 31479292

Showing the first eight; more decompositions exist.
