Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461658, here are decompositions:

5 + 31461653 = 31461658
17 + 31461641 = 31461658
89 + 31461569 = 31461658
101 + 31461557 = 31461658
317 + 31461341 = 31461658
467 + 31461191 = 31461658
479 + 31461179 = 31461658
509 + 31461149 = 31461658

Showing the first eight; more decompositions exist.
