Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541654, here are decompositions:

3 + 31541651 = 31541654
43 + 31541611 = 31541654
73 + 31541581 = 31541654
97 + 31541557 = 31541654
127 + 31541527 = 31541654
307 + 31541347 = 31541654
373 + 31541281 = 31541654
421 + 31541233 = 31541654

Showing the first eight; more decompositions exist.
