Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446094, here are decompositions:

41 + 31446053 = 31446094
83 + 31446011 = 31446094
137 + 31445957 = 31446094
233 + 31445861 = 31446094
401 + 31445693 = 31446094
431 + 31445663 = 31446094
443 + 31445651 = 31446094
521 + 31445573 = 31446094

Showing the first eight; more decompositions exist.
