Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497846, here are decompositions:

19 + 31497827 = 31497846
43 + 31497803 = 31497846
73 + 31497773 = 31497846
89 + 31497757 = 31497846
109 + 31497737 = 31497846
139 + 31497707 = 31497846
167 + 31497679 = 31497846
173 + 31497673 = 31497846

Showing the first eight; more decompositions exist.
