Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931242, here are decompositions:

5 + 931237 = 931242
29 + 931213 = 931242
43 + 931199 = 931242
61 + 931181 = 931242
73 + 931169 = 931242
79 + 931163 = 931242
89 + 931153 = 931242
113 + 931129 = 931242

Showing the first eight; more decompositions exist.
