Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540602, here are decompositions:

29 + 31540573 = 31540602
73 + 31540529 = 31540602
101 + 31540501 = 31540602
103 + 31540499 = 31540602
109 + 31540493 = 31540602
113 + 31540489 = 31540602
131 + 31540471 = 31540602
239 + 31540363 = 31540602

Showing the first eight; more decompositions exist.
