Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446190, here are decompositions:

23 + 31446167 = 31446190
59 + 31446131 = 31446190
89 + 31446101 = 31446190
137 + 31446053 = 31446190
179 + 31446011 = 31446190
233 + 31445957 = 31446190
401 + 31445789 = 31446190
467 + 31445723 = 31446190

Showing the first eight; more decompositions exist.
