Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576352, here are decompositions:

151 + 31576201 = 31576352
349 + 31576003 = 31576352
523 + 31575829 = 31576352
853 + 31575499 = 31576352
883 + 31575469 = 31576352
919 + 31575433 = 31576352
991 + 31575361 = 31576352
1051 + 31575301 = 31576352

Showing the first eight; more decompositions exist.
