Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479174, here are decompositions:

43 + 31479131 = 31479174
47 + 31479127 = 31479174
73 + 31479101 = 31479174
101 + 31479073 = 31479174
113 + 31479061 = 31479174
157 + 31479017 = 31479174
173 + 31479001 = 31479174
191 + 31478983 = 31479174

Showing the first eight; more decompositions exist.
