Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447174, here are decompositions:

41 + 31447133 = 31447174
71 + 31447103 = 31447174
131 + 31447043 = 31447174
173 + 31447001 = 31447174
191 + 31446983 = 31447174
257 + 31446917 = 31447174
281 + 31446893 = 31447174
431 + 31446743 = 31447174

Showing the first eight; more decompositions exist.
