Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462482, here are decompositions:

11 + 31462471 = 31462482
31 + 31462451 = 31462482
41 + 31462441 = 31462482
43 + 31462439 = 31462482
101 + 31462381 = 31462482
109 + 31462373 = 31462482
131 + 31462351 = 31462482
193 + 31462289 = 31462482

Showing the first eight; more decompositions exist.
