Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541054, here are decompositions:

3 + 31541051 = 31541054
7 + 31541047 = 31541054
37 + 31541017 = 31541054
241 + 31540813 = 31541054
271 + 31540783 = 31541054
331 + 31540723 = 31541054
397 + 31540657 = 31541054
613 + 31540441 = 31541054

Showing the first eight; more decompositions exist.
