Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487602, here are decompositions:

59 + 31487543 = 31487602
89 + 31487513 = 31487602
131 + 31487471 = 31487602
191 + 31487411 = 31487602
233 + 31487369 = 31487602
239 + 31487363 = 31487602
431 + 31487171 = 31487602
449 + 31487153 = 31487602

Showing the first eight; more decompositions exist.
