Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446650, here are decompositions:

43 + 31446607 = 31446650
97 + 31446553 = 31446650
211 + 31446439 = 31446650
223 + 31446427 = 31446650
283 + 31446367 = 31446650
397 + 31446253 = 31446650
409 + 31446241 = 31446650
421 + 31446229 = 31446650

Showing the first eight; more decompositions exist.
