Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603758, here are decompositions:

7 + 31603751 = 31603758
19 + 31603739 = 31603758
37 + 31603721 = 31603758
41 + 31603717 = 31603758
47 + 31603711 = 31603758
101 + 31603657 = 31603758
149 + 31603609 = 31603758
181 + 31603577 = 31603758

Showing the first eight; more decompositions exist.
