Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532654, here are decompositions:

61 + 31532593 = 31532654
67 + 31532587 = 31532654
73 + 31532581 = 31532654
103 + 31532551 = 31532654
157 + 31532497 = 31532654
313 + 31532341 = 31532654
331 + 31532323 = 31532654
487 + 31532167 = 31532654

Showing the first eight; more decompositions exist.
