Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546890, here are decompositions:

29 + 31546861 = 31546890
43 + 31546847 = 31546890
47 + 31546843 = 31546890
59 + 31546831 = 31546890
73 + 31546817 = 31546890
83 + 31546807 = 31546890
101 + 31546789 = 31546890
131 + 31546759 = 31546890

Showing the first eight; more decompositions exist.
