Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576344, here are decompositions:

61 + 31576283 = 31576344
83 + 31576261 = 31576344
103 + 31576241 = 31576344
113 + 31576231 = 31576344
157 + 31576187 = 31576344
181 + 31576163 = 31576344
223 + 31576121 = 31576344
227 + 31576117 = 31576344

Showing the first eight; more decompositions exist.
