Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522802, here are decompositions:

109 + 31522693 = 31522802
139 + 31522663 = 31522802
211 + 31522591 = 31522802
439 + 31522363 = 31522802
463 + 31522339 = 31522802
673 + 31522129 = 31522802
811 + 31521991 = 31522802
823 + 31521979 = 31522802

Showing the first eight; more decompositions exist.
