Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462890, here are decompositions:

13 + 31462877 = 31462890
59 + 31462831 = 31462890
79 + 31462811 = 31462890
83 + 31462807 = 31462890
97 + 31462793 = 31462890
131 + 31462759 = 31462890
139 + 31462751 = 31462890
167 + 31462723 = 31462890

Showing the first eight; more decompositions exist.
