Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446454, here are decompositions:

113 + 31446341 = 31446454
131 + 31446323 = 31446454
197 + 31446257 = 31446454
227 + 31446227 = 31446454
353 + 31446101 = 31446454
401 + 31446053 = 31446454
443 + 31446011 = 31446454
563 + 31445891 = 31446454

Showing the first eight; more decompositions exist.
