Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542818, here are decompositions:

7 + 31542811 = 31542818
19 + 31542799 = 31542818
31 + 31542787 = 31542818
271 + 31542547 = 31542818
331 + 31542487 = 31542818
379 + 31542439 = 31542818
421 + 31542397 = 31542818
751 + 31542067 = 31542818

Showing the first eight; more decompositions exist.
