Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446732, here are decompositions:

43 + 31446689 = 31446732
139 + 31446593 = 31446732
179 + 31446553 = 31446732
199 + 31446533 = 31446732
241 + 31446491 = 31446732
271 + 31446461 = 31446732
293 + 31446439 = 31446732
409 + 31446323 = 31446732

Showing the first eight; more decompositions exist.
