Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446998, here are decompositions:

61 + 31446937 = 31446998
127 + 31446871 = 31446998
139 + 31446859 = 31446998
151 + 31446847 = 31446998
229 + 31446769 = 31446998
241 + 31446757 = 31446998
571 + 31446427 = 31446998
631 + 31446367 = 31446998

Showing the first eight; more decompositions exist.
