Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554652, here are decompositions:

11 + 31554641 = 31554652
83 + 31554569 = 31554652
113 + 31554539 = 31554652
179 + 31554473 = 31554652
251 + 31554401 = 31554652
491 + 31554161 = 31554652
509 + 31554143 = 31554652
641 + 31554011 = 31554652

Showing the first eight; more decompositions exist.
