Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446070, here are decompositions:

3 + 31446067 = 31446070
17 + 31446053 = 31446070
59 + 31446011 = 31446070
113 + 31445957 = 31446070
179 + 31445891 = 31446070
281 + 31445789 = 31446070
347 + 31445723 = 31446070
389 + 31445681 = 31446070

Showing the first eight; more decompositions exist.
