Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462862, here are decompositions:

31 + 31462831 = 31462862
103 + 31462759 = 31462862
139 + 31462723 = 31462862
271 + 31462591 = 31462862
283 + 31462579 = 31462862
331 + 31462531 = 31462862
421 + 31462441 = 31462862
499 + 31462363 = 31462862

Showing the first eight; more decompositions exist.
