Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446130, here are decompositions:

29 + 31446101 = 31446130
173 + 31445957 = 31446130
239 + 31445891 = 31446130
269 + 31445861 = 31446130
281 + 31445849 = 31446130
449 + 31445681 = 31446130
467 + 31445663 = 31446130
479 + 31445651 = 31446130

Showing the first eight; more decompositions exist.
