Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447262, here are decompositions:

73 + 31447189 = 31447262
163 + 31447099 = 31447262
181 + 31447081 = 31447262
193 + 31447069 = 31447262
241 + 31447021 = 31447262
313 + 31446949 = 31447262
409 + 31446853 = 31447262
523 + 31446739 = 31447262

Showing the first eight; more decompositions exist.
