Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534658, here are decompositions:

7 + 31534651 = 31534658
61 + 31534597 = 31534658
97 + 31534561 = 31534658
157 + 31534501 = 31534658
229 + 31534429 = 31534658
541 + 31534117 = 31534658
601 + 31534057 = 31534658
607 + 31534051 = 31534658

Showing the first eight; more decompositions exist.
