Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479102, here are decompositions:

19 + 31479083 = 31479102
29 + 31479073 = 31479102
41 + 31479061 = 31479102
71 + 31479031 = 31479102
101 + 31479001 = 31479102
191 + 31478911 = 31479102
251 + 31478851 = 31479102
271 + 31478831 = 31479102

Showing the first eight; more decompositions exist.
