Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480294, here are decompositions:

5 + 31480289 = 31480294
191 + 31480103 = 31480294
233 + 31480061 = 31480294
347 + 31479947 = 31480294
491 + 31479803 = 31480294
557 + 31479737 = 31480294
647 + 31479647 = 31480294
701 + 31479593 = 31480294

Showing the first eight; more decompositions exist.
