Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535044, here are decompositions:

11 + 31535033 = 31535044
83 + 31534961 = 31535044
131 + 31534913 = 31535044
173 + 31534871 = 31535044
257 + 31534787 = 31535044
293 + 31534751 = 31535044
353 + 31534691 = 31535044
491 + 31534553 = 31535044

Showing the first eight; more decompositions exist.
