Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481034, here are decompositions:

23 + 31481011 = 31481034
61 + 31480973 = 31481034
71 + 31480963 = 31481034
173 + 31480861 = 31481034
241 + 31480793 = 31481034
271 + 31480763 = 31481034
353 + 31480681 = 31481034
593 + 31480441 = 31481034

Showing the first eight; more decompositions exist.
