Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543862, here are decompositions:

3 + 31543859 = 31543862
19 + 31543843 = 31543862
79 + 31543783 = 31543862
139 + 31543723 = 31543862
151 + 31543711 = 31543862
193 + 31543669 = 31543862
283 + 31543579 = 31543862
331 + 31543531 = 31543862

Showing the first eight; more decompositions exist.
