Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494844, here are decompositions:

107 + 31494737 = 31494844
131 + 31494713 = 31494844
137 + 31494707 = 31494844
233 + 31494611 = 31494844
263 + 31494581 = 31494844
347 + 31494497 = 31494844
401 + 31494443 = 31494844
443 + 31494401 = 31494844

Showing the first eight; more decompositions exist.
