Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482756, here are decompositions:

13 + 31482743 = 31482756
47 + 31482709 = 31482756
73 + 31482683 = 31482756
89 + 31482667 = 31482756
113 + 31482643 = 31482756
139 + 31482617 = 31482756
157 + 31482599 = 31482756
197 + 31482559 = 31482756

Showing the first eight; more decompositions exist.
