Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497244, here are decompositions:

173 + 31497071 = 31497244
281 + 31496963 = 31497244
461 + 31496783 = 31497244
503 + 31496741 = 31497244
677 + 31496567 = 31497244
827 + 31496417 = 31497244
983 + 31496261 = 31497244
1103 + 31496141 = 31497244

Showing the first eight; more decompositions exist.
