Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477652, here are decompositions:

103 + 31477549 = 31477652
109 + 31477543 = 31477652
139 + 31477513 = 31477652
223 + 31477429 = 31477652
229 + 31477423 = 31477652
331 + 31477321 = 31477652
439 + 31477213 = 31477652
541 + 31477111 = 31477652

Showing the first eight; more decompositions exist.
