Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540522, here are decompositions:

23 + 31540499 = 31540522
29 + 31540493 = 31540522
179 + 31540343 = 31540522
281 + 31540241 = 31540522
311 + 31540211 = 31540522
359 + 31540163 = 31540522
491 + 31540031 = 31540522
509 + 31540013 = 31540522

Showing the first eight; more decompositions exist.
