Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540552, here are decompositions:

23 + 31540529 = 31540552
53 + 31540499 = 31540552
59 + 31540493 = 31540552
311 + 31540241 = 31540552
389 + 31540163 = 31540552
443 + 31540109 = 31540552
521 + 31540031 = 31540552
839 + 31539713 = 31540552

Showing the first eight; more decompositions exist.
