Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449932, here are decompositions:

61 + 31449871 = 31449932
79 + 31449853 = 31449932
109 + 31449823 = 31449932
181 + 31449751 = 31449932
193 + 31449739 = 31449932
313 + 31449619 = 31449932
379 + 31449553 = 31449932
433 + 31449499 = 31449932

Showing the first eight; more decompositions exist.
