Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535444, here are decompositions:

67 + 31535377 = 31535444
103 + 31535341 = 31535444
181 + 31535263 = 31535444
211 + 31535233 = 31535444
271 + 31535173 = 31535444
313 + 31535131 = 31535444
331 + 31535113 = 31535444
337 + 31535107 = 31535444

Showing the first eight; more decompositions exist.
