Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460834, here are decompositions:

3 + 31460831 = 31460834
43 + 31460791 = 31460834
157 + 31460677 = 31460834
283 + 31460551 = 31460834
337 + 31460497 = 31460834
421 + 31460413 = 31460834
487 + 31460347 = 31460834
541 + 31460293 = 31460834

Showing the first eight; more decompositions exist.
