Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541446, here are decompositions:

17 + 31541429 = 31541446
29 + 31541417 = 31541446
47 + 31541399 = 31541446
149 + 31541297 = 31541446
179 + 31541267 = 31541446
317 + 31541129 = 31541446
467 + 31540979 = 31541446
659 + 31540787 = 31541446

Showing the first eight; more decompositions exist.
