Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497134, here are decompositions:

7 + 31497127 = 31497134
127 + 31497007 = 31497134
157 + 31496977 = 31497134
271 + 31496863 = 31497134
307 + 31496827 = 31497134
457 + 31496677 = 31497134
463 + 31496671 = 31497134
523 + 31496611 = 31497134

Showing the first eight; more decompositions exist.
