Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544070, here are decompositions:

13 + 31544057 = 31544070
17 + 31544053 = 31544070
29 + 31544041 = 31544070
31 + 31544039 = 31544070
37 + 31544033 = 31544070
59 + 31544011 = 31544070
73 + 31543997 = 31544070
79 + 31543991 = 31544070

Showing the first eight; more decompositions exist.
