Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473396, here are decompositions:

37 + 31473359 = 31473396
83 + 31473313 = 31473396
113 + 31473283 = 31473396
179 + 31473217 = 31473396
193 + 31473203 = 31473396
223 + 31473173 = 31473396
233 + 31473163 = 31473396
313 + 31473083 = 31473396

Showing the first eight; more decompositions exist.
