Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461754, here are decompositions:

11 + 31461743 = 31461754
17 + 31461737 = 31461754
101 + 31461653 = 31461754
113 + 31461641 = 31461754
197 + 31461557 = 31461754
461 + 31461293 = 31461754
563 + 31461191 = 31461754
593 + 31461161 = 31461754

Showing the first eight; more decompositions exist.
