Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479224, here are decompositions:

97 + 31479127 = 31479224
151 + 31479073 = 31479224
163 + 31479061 = 31479224
193 + 31479031 = 31479224
223 + 31479001 = 31479224
241 + 31478983 = 31479224
313 + 31478911 = 31479224
373 + 31478851 = 31479224

Showing the first eight; more decompositions exist.
