Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558494, here are decompositions:

5 + 31558489 = 31558494
31 + 31558463 = 31558494
41 + 31558453 = 31558494
61 + 31558433 = 31558494
103 + 31558391 = 31558494
113 + 31558381 = 31558494
157 + 31558337 = 31558494
167 + 31558327 = 31558494

Showing the first eight; more decompositions exist.
