Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480252, here are decompositions:

149 + 31480103 = 31480252
173 + 31480079 = 31480252
191 + 31480061 = 31480252
233 + 31480019 = 31480252
431 + 31479821 = 31480252
449 + 31479803 = 31480252
509 + 31479743 = 31480252
659 + 31479593 = 31480252

Showing the first eight; more decompositions exist.
