Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480034, here are decompositions:

13 + 31480021 = 31480034
73 + 31479961 = 31480034
241 + 31479793 = 31480034
277 + 31479757 = 31480034
337 + 31479697 = 31480034
457 + 31479577 = 31480034
577 + 31479457 = 31480034
613 + 31479421 = 31480034

Showing the first eight; more decompositions exist.
