Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541002, here are decompositions:

11 + 31540991 = 31541002
23 + 31540979 = 31541002
41 + 31540961 = 31541002
131 + 31540871 = 31541002
179 + 31540823 = 31541002
293 + 31540709 = 31541002
359 + 31540643 = 31541002
503 + 31540499 = 31541002

Showing the first eight; more decompositions exist.
