Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504170, here are decompositions:

37 + 31504133 = 31504170
41 + 31504129 = 31504170
43 + 31504127 = 31504170
67 + 31504103 = 31504170
73 + 31504097 = 31504170
83 + 31504087 = 31504170
157 + 31504013 = 31504170
193 + 31503977 = 31504170

Showing the first eight; more decompositions exist.
