Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541070, here are decompositions:

19 + 31541051 = 31541070
23 + 31541047 = 31541070
31 + 31541039 = 31541070
53 + 31541017 = 31541070
79 + 31540991 = 31541070
109 + 31540961 = 31541070
131 + 31540939 = 31541070
149 + 31540921 = 31541070

Showing the first eight; more decompositions exist.
