Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446652, here are decompositions:

11 + 31446641 = 31446652
59 + 31446593 = 31446652
89 + 31446563 = 31446652
191 + 31446461 = 31446652
311 + 31446341 = 31446652
401 + 31446251 = 31446652
521 + 31446131 = 31446652
599 + 31446053 = 31446652

Showing the first eight; more decompositions exist.
