Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450932, here are decompositions:

41 + 31450891 = 31450932
53 + 31450879 = 31450932
89 + 31450843 = 31450932
103 + 31450829 = 31450932
109 + 31450823 = 31450932
131 + 31450801 = 31450932
151 + 31450781 = 31450932
193 + 31450739 = 31450932

Showing the first eight; more decompositions exist.
