Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452994, here are decompositions:

17 + 31452977 = 31452994
191 + 31452803 = 31452994
263 + 31452731 = 31452994
311 + 31452683 = 31452994
317 + 31452677 = 31452994
467 + 31452527 = 31452994
593 + 31452401 = 31452994
653 + 31452341 = 31452994

Showing the first eight; more decompositions exist.
