Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473434, here are decompositions:

37 + 31473397 = 31473434
103 + 31473331 = 31473434
151 + 31473283 = 31473434
193 + 31473241 = 31473434
271 + 31473163 = 31473434
283 + 31473151 = 31473434
367 + 31473067 = 31473434
373 + 31473061 = 31473434

Showing the first eight; more decompositions exist.
