Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504236, here are decompositions:

7 + 31504229 = 31504236
17 + 31504219 = 31504236
47 + 31504189 = 31504236
53 + 31504183 = 31504236
103 + 31504133 = 31504236
107 + 31504129 = 31504236
109 + 31504127 = 31504236
139 + 31504097 = 31504236

Showing the first eight; more decompositions exist.
