Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541132, here are decompositions:

3 + 31541129 = 31541132
19 + 31541113 = 31541132
31 + 31541101 = 31541132
61 + 31541071 = 31541132
193 + 31540939 = 31541132
211 + 31540921 = 31541132
349 + 31540783 = 31541132
409 + 31540723 = 31541132

Showing the first eight; more decompositions exist.
