Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480934, here are decompositions:

61 + 31480873 = 31480934
73 + 31480861 = 31480934
241 + 31480693 = 31480934
313 + 31480621 = 31480934
733 + 31480201 = 31480934
1117 + 31479817 = 31480934
1237 + 31479697 = 31480934
1597 + 31479337 = 31480934

Showing the first eight; more decompositions exist.
