Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541362, here are decompositions:

3 + 31541359 = 31541362
233 + 31541129 = 31541362
311 + 31541051 = 31541362
383 + 31540979 = 31541362
401 + 31540961 = 31541362
491 + 31540871 = 31541362
653 + 31540709 = 31541362
683 + 31540679 = 31541362

Showing the first eight; more decompositions exist.
