Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541092, here are decompositions:

41 + 31541051 = 31541092
53 + 31541039 = 31541092
71 + 31541021 = 31541092
101 + 31540991 = 31541092
113 + 31540979 = 31541092
131 + 31540961 = 31541092
269 + 31540823 = 31541092
383 + 31540709 = 31541092

Showing the first eight; more decompositions exist.
