Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539752, here are decompositions:

103 + 31539649 = 31539752
109 + 31539643 = 31539752
229 + 31539523 = 31539752
313 + 31539439 = 31539752
331 + 31539421 = 31539752
421 + 31539331 = 31539752
463 + 31539289 = 31539752
523 + 31539229 = 31539752

Showing the first eight; more decompositions exist.
