Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446136, here are decompositions:

3 + 31446133 = 31446136
5 + 31446131 = 31446136
83 + 31446053 = 31446136
179 + 31445957 = 31446136
347 + 31445789 = 31446136
443 + 31445693 = 31446136
563 + 31445573 = 31446136
593 + 31445543 = 31446136

Showing the first eight; more decompositions exist.
