Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504242, here are decompositions:

13 + 31504229 = 31504242
23 + 31504219 = 31504242
41 + 31504201 = 31504242
53 + 31504189 = 31504242
59 + 31504183 = 31504242
109 + 31504133 = 31504242
113 + 31504129 = 31504242
139 + 31504103 = 31504242

Showing the first eight; more decompositions exist.
