Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540846, here are decompositions:

23 + 31540823 = 31540846
59 + 31540787 = 31540846
137 + 31540709 = 31540846
167 + 31540679 = 31540846
317 + 31540529 = 31540846
347 + 31540499 = 31540846
353 + 31540493 = 31540846
503 + 31540343 = 31540846

Showing the first eight; more decompositions exist.
