Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535648, here are decompositions:

97 + 31535551 = 31535648
181 + 31535467 = 31535648
229 + 31535419 = 31535648
271 + 31535377 = 31535648
307 + 31535341 = 31535648
337 + 31535311 = 31535648
421 + 31535227 = 31535648
541 + 31535107 = 31535648

Showing the first eight; more decompositions exist.
