Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479092, here are decompositions:

19 + 31479073 = 31479092
31 + 31479061 = 31479092
61 + 31479031 = 31479092
109 + 31478983 = 31479092
181 + 31478911 = 31479092
241 + 31478851 = 31479092
373 + 31478719 = 31479092
499 + 31478593 = 31479092

Showing the first eight; more decompositions exist.
