Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535796, here are decompositions:

43 + 31535753 = 31535796
79 + 31535717 = 31535796
139 + 31535657 = 31535796
157 + 31535639 = 31535796
163 + 31535633 = 31535796
293 + 31535503 = 31535796
367 + 31535429 = 31535796
373 + 31535423 = 31535796

Showing the first eight; more decompositions exist.
