Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447088, here are decompositions:

7 + 31447081 = 31447088
19 + 31447069 = 31447088
61 + 31447027 = 31447088
67 + 31447021 = 31447088
139 + 31446949 = 31447088
151 + 31446937 = 31447088
229 + 31446859 = 31447088
241 + 31446847 = 31447088

Showing the first eight; more decompositions exist.
