Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534874, here are decompositions:

3 + 31534871 = 31534874
43 + 31534831 = 31534874
73 + 31534801 = 31534874
223 + 31534651 = 31534874
277 + 31534597 = 31534874
313 + 31534561 = 31534874
331 + 31534543 = 31534874
373 + 31534501 = 31534874

Showing the first eight; more decompositions exist.
