Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475174, here are decompositions:

43 + 31475131 = 31475174
67 + 31475107 = 31475174
103 + 31475071 = 31475174
193 + 31474981 = 31475174
307 + 31474867 = 31475174
373 + 31474801 = 31475174
397 + 31474777 = 31475174
487 + 31474687 = 31475174

Showing the first eight; more decompositions exist.
