Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446124, here are decompositions:

23 + 31446101 = 31446124
71 + 31446053 = 31446124
113 + 31446011 = 31446124
167 + 31445957 = 31446124
233 + 31445891 = 31446124
263 + 31445861 = 31446124
401 + 31445723 = 31446124
431 + 31445693 = 31446124

Showing the first eight; more decompositions exist.
