Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535708, here are decompositions:

37 + 31535671 = 31535708
157 + 31535551 = 31535708
241 + 31535467 = 31535708
331 + 31535377 = 31535708
367 + 31535341 = 31535708
397 + 31535311 = 31535708
577 + 31535131 = 31535708
601 + 31535107 = 31535708

Showing the first eight; more decompositions exist.
