Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541404, here are decompositions:

3 + 31541401 = 31541404
5 + 31541399 = 31541404
107 + 31541297 = 31541404
137 + 31541267 = 31541404
263 + 31541141 = 31541404
353 + 31541051 = 31541404
383 + 31541021 = 31541404
443 + 31540961 = 31541404

Showing the first eight; more decompositions exist.
