Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446684, here are decompositions:

43 + 31446641 = 31446684
127 + 31446557 = 31446684
131 + 31446553 = 31446684
151 + 31446533 = 31446684
193 + 31446491 = 31446684
223 + 31446461 = 31446684
257 + 31446427 = 31446684
317 + 31446367 = 31446684

Showing the first eight; more decompositions exist.
