Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480012, here are decompositions:

131 + 31479881 = 31480012
191 + 31479821 = 31480012
269 + 31479743 = 31480012
293 + 31479719 = 31480012
419 + 31479593 = 31480012
461 + 31479551 = 31480012
521 + 31479491 = 31480012
593 + 31479419 = 31480012

Showing the first eight; more decompositions exist.
