Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535774, here are decompositions:

103 + 31535671 = 31535774
181 + 31535593 = 31535774
223 + 31535551 = 31535774
271 + 31535503 = 31535774
307 + 31535467 = 31535774
397 + 31535377 = 31535774
433 + 31535341 = 31535774
463 + 31535311 = 31535774

Showing the first eight; more decompositions exist.
